The universe is commonly defined as the totality of everything that exists, including all space, time, matter, energy, planets, stars, galaxies, intergalactic space, and beyond. Definitions and usage vary and similar terms include the cosmos, the world and nature. Scientific observation of earlier stages in the development of the universe, which can be seen at great distances, suggests that the universe has been governed by the same physical laws and constants throughout most of its extent and history. There are various multiverse theories, in which physicists have suggested the universe is one among many universes that likewise exist.
According to the prevailing scientific model of the universe, known as the Big Bang, the universe expanded from an extremely hot, dense phase called the Planck epoch, in which all the matter and energy of the observable universe was concentrated. Since the Planck epoch, the universe has been expanding to its present form, possibly with a brief period (less than 10−32 seconds) of cosmic inflation. Several independent experimental measurements support this theoretical expansion and, more generally, the Big Bang theory. Recent observations indicate that this expansion is accelerating because of dark energy, and that most of the matter in the universe may be in a form which cannot be detected by present instruments, and so is not accounted for in the present models of the universe; this has been named dark matter. The imprecision of current observations has hindered predictions of the ultimate fate of the universe.
Current interpretations of astronomical observations indicate that the age of the universe is 13.75 ± 0.17 billion years, and that the diameter of the observable universe is at least 93 billion light years or metres. According to general relativity, space can expand faster than the speed of light, although we can view only a small portion of the universe due to the limitation imposed by light speed. Since we cannot observe space beyond the limitations of light (or any electromagnetic radiation), it is uncertain whether the size of the universe is finite or infinite.
An alternative interpretation of unvorsum is "everything rotated as one" or "everything rotated by one". In this sense, it may be considered a translation of an earlier Greek word for the universe, , (periforá, "circumambulation"), originally used to describe a course of a meal, the food being carried around the circle of dinner guests. This Greek word refers to celestial spheres, an early Greek model of the universe. Regarding Plato's Metaphor of the sun, Aristotle suggests that the rotation of the sphere of fixed stars inspired by the prime mover, motivates, in turn, terrestrial change via the Sun. Careful astronomical and physical measurements (such as the Foucault pendulum) are required to prove the Earth rotates on its axis.
A term for "universe" in ancient Greece was (tó pán, The All, Pan (mythology)). Related terms were matter, (, tó ólon, see also Hyle, lit. wood) and place (, tó kenón). Other synonyms for the universe among the ancient Greek philosophers included (cosmos) and (meaning Nature, from which we derive the word physics). The same synonyms are found in Latin authors (totum, mundus, natura) and survive in modern languages, e.g., the German words Das All, Weltall, and Natur for universe. The same synonyms are found in English, such as everything (as in the theory of everything), the cosmos (as in cosmology), the world (as in the many-worlds hypothesis), and Nature (as in natural laws or natural philosophy).
The broadest definition of the universe can be found in De divisione naturae by the medieval philosopher and theologian Johannes Scotus Eriugena, who defined it as simply everything: everything that is created and everything that is not created. In the path integral formulation of Richard Feynman, the probability amplitudes for the various outcomes of an experiment given a perfectly defined initial state of the system are determined by summing over all possible histories (paths) by which the system could progress from the initial to final state.
More customarily, the universe is defined as everything that exists, (has existed, and will exist) . According to our current understanding, the universe consists of three principles: spacetime, forms of energy, including momentum and matter, and the physical laws that relate them.
It is possible to conceive of disconnected space-times, each existing but unable to interact with one another. An easily visualized metaphor is a group of separate soap bubbles, in which observers living on one soap bubble cannot interact with those on other soap bubbles, even in principle. According to one common terminology, each "soap bubble" of space-time is denoted as a universe, whereas our particular space-time is denoted as the universe, just as we call our moon the Moon. The entire collection of these separate space-times is denoted as the multiverse. In principle, the other unconnected universes may have different dimensionalities and topologies of space-time, different forms of matter and energy, and different physical laws and physical constants, although such possibilities are currently speculative.
According to a still-more-restrictive definition, the universe is everything within our connected space-time that could have a chance to interact with us and vice versa. According to the general theory of relativity, some regions of space may never interact with ours even in the lifetime of the universe, due to the finite speed of light and the ongoing expansion of space. For example, radio messages sent from Earth may never reach some regions of space, even if the universe would live forever; space may expand faster than light can traverse it. It is worth emphasizing that those distant regions of space are taken to exist and be part of reality as much as we are; yet we can never interact with them. The spatial region within which we can affect and be affected is denoted as the observable universe. Strictly speaking, the observable universe depends on the location of the observer. By traveling, an observer can come into contact with a greater region of space-time than an observer who remains still, so that the observable universe for the former is larger than for the latter. Nevertheless, even the most rapid traveler will not be able to interact with all of space. Typically, the observable universe is taken to mean the universe observable from our vantage point in the Milky Way Galaxy.
==Size, age, contents, structure, and laws==
The universe is immensely large and possibly infinite in volume. The region visible from Earth (the observable universe) is a sphere with a radius of about 46 billion light years, based on where the expansion of space has taken the most distant objects observed. For comparison, the diameter of a typical galaxy is only 30,000 light-years, and the typical distance between two neighboring galaxies is only 3 million light-years. As an example, our Milky Way Galaxy is roughly 100,000 light years in diameter, and our nearest sister galaxy, the Andromeda Galaxy, is located roughly 2.5 million light years away. There are probably more than 100 billion (1011) galaxies in the observable universe. Typical galaxies range from dwarfs with as few as ten million (107) stars up to giants with one trillion (1012) stars, all orbiting the galaxy's center of mass. Thus, a very rough estimate from these numbers would suggest there are around one sextillion (1021) stars in the observable universe; though a 2010 study by astronomers resulted in a figure of 300 sextillion (3).
The observable matter is spread homogeneously (uniformly) throughout the universe, when averaged over distances longer than 300 million light-years. However, on smaller length-scales, matter is observed to form "clumps", i.e., to cluster hierarchically; many atoms are condensed into stars, most stars into galaxies, most galaxies into clusters, superclusters and, finally, the largest-scale structures such as the Great Wall of galaxies. The observable matter of the universe is also spread isotropically, meaning that no direction of observation seems different from any other; each region of the sky has roughly the same content. The universe is also bathed in a highly isotropic microwave radiation that corresponds to a thermal equilibrium blackbody spectrum of roughly 2.725-kelvins. The hypothesis that the large-scale universe is homogeneous and isotropic is known as the cosmological principle, which is supported by astronomical observations.
The present overall density of the universe is very low, roughly 9.9 × 10−30 grams per cubic centimetre. This mass-energy appears to consist of 73% dark energy, 23% cold dark matter and 4% ordinary matter. Thus the density of atoms is on the order of a single hydrogen atom for every four cubic meters of volume. The properties of dark energy and dark matter are largely unknown. Dark matter gravitates as ordinary matter, and thus works to slow the expansion of the universe; by contrast, dark energy accelerates its expansion.
The most precise estimate of the universe's age is 13.73±0.12 billion years old, based on observations of the cosmic microwave background radiation. Independent estimates (based on measurements such as radioactive dating) agree, although they are less precise, ranging from 11 to 20 billion years to 13–15 billion years. The universe has not been the same at all times in its history; for example, the relative populations of quasars and galaxies have changed and space itself appears to have expanded. This expansion accounts for how Earth-bound scientists can observe the light from a galaxy 30 billion light years away, even if that light has traveled for only 13 billion years; the very space between them has expanded. This expansion is consistent with the observation that the light from distant galaxies has been redshifted; the photons emitted have been stretched to longer wavelengths and lower frequency during their journey. The rate of this spatial expansion is accelerating, based on studies of Type Ia supernovae and corroborated by other data.
The relative fractions of different chemical elements — particularly the lightest atoms such as hydrogen, deuterium and helium — seem to be identical throughout the universe and throughout its observable history. The universe seems to have much more matter than antimatter, an asymmetry possibly related to the observations of CP violation. The universe appears to have no net electric charge, and therefore gravity appears to be the dominant interaction on cosmological length scales. The universe also appears to have neither net momentum nor angular momentum. The absence of net charge and momentum would follow from accepted physical laws (Gauss's law and the non-divergence of the stress-energy-momentum pseudotensor, respectively), if the universe were finite.
The universe appears to have a smooth space-time continuum consisting of three spatial dimensions and one temporal (time) dimension. On the average, space is observed to be very nearly flat (close to zero curvature), meaning that Euclidean geometry is experimentally true with high accuracy throughout most of the Universe. Spacetime also appears to have a simply connected topology, at least on the length-scale of the observable universe. However, present observations cannot exclude the possibilities that the universe has more dimensions and that its spacetime may have a multiply connected global topology, in analogy with the cylindrical or toroidal topologies of two-dimensional spaces.
The universe appears to behave in a manner that regularly follows a set of physical laws and physical constants. According to the prevailing Standard Model of physics, all matter is composed of three generations of leptons and quarks, both of which are fermions. These elementary particles interact via at most three fundamental interactions: the electroweak interaction which includes electromagnetism and the weak nuclear force; the strong nuclear force described by quantum chromodynamics; and gravity, which is best described at present by general relativity. The first two interactions can be described by renormalized quantum field theory, and are mediated by gauge bosons that correspond to a particular type of gauge symmetry. A renormalized quantum field theory of general relativity has not yet been achieved, although various forms of string theory seem promising. The theory of special relativity is believed to hold throughout the universe, provided that the spatial and temporal length scales are sufficiently short; otherwise, the more general theory of general relativity must be applied. There is no explanation for the particular values that physical constants appear to have throughout our universe, such as Planck's constant h or the gravitational constant G. Several conservation laws have been identified, such as the conservation of charge, momentum, angular momentum and energy; in many cases, these conservation laws can be related to symmetries or mathematical identities.
It appears that many of the properties of the universe have special values in the sense that a universe where these properties only differ slightly would not be able to support intelligent life. Not all scientists agree that this fine-tuning exists. In particular, it is not known under what conditions intelligent life could form and what form or shape that would take. A relevant observation in this discussion is that for an observer to exist to observe fine-tuning, the universe must be able to support intelligent life. As such the conditional probability of observing a universe that is fine-tuned to support intelligent life is 1. This observation is known as the anthropic principle and is particularly relevant if the creation of the universe was probabilistic or if multiple universes with a variety of properties exist (see below).
Many models of the cosmos (cosmologies) and its origin (cosmogonies) have been proposed, based on the then-available data and conceptions of the universe. Historically, cosmologies and cosmogonies were based on narratives of gods acting in various ways. Theories of an impersonal universe governed by physical laws were first proposed by the Greeks and Indians. Over the centuries, improvements in astronomical observations and theories of motion and gravitation led to ever more accurate descriptions of the universe. The modern era of cosmology began with Albert Einstein's 1915 general theory of relativity, which made it possible to quantitatively predict the origin, evolution, and conclusion of the universe as a whole. Most modern, accepted theories of cosmology are based on general relativity and, more specifically, the predicted Big Bang; however, still more careful measurements are required to determine which theory is correct.
Many cultures have stories describing the origin of the world, which may be roughly grouped into common types. In one type of story, the world is born from a world egg; such stories include the Finnish epic poem Kalevala, the Chinese story of Pangu or the Indian Brahmanda Purana. In related stories, the creation idea is caused by a single entity emanating or producing something by him- or herself, as in the Tibetan Buddhism concept of Adi-Buddha, the ancient Greek story of Gaia (Mother Earth), the Aztec goddess Coatlicue myth, the ancient Egyptian god Atum story, or the Genesis creation narrative. In another type of story, the world is created from the union of male and female deities, as in the Maori story of Rangi and Papa. In other stories, the universe is created by crafting it from pre-existing materials, such as the corpse of a dead god — as from Tiamat in the Babylonian epic Enuma Elish or from the giant Ymir in Norse mythology – or from chaotic materials, as in Izanagi and Izanami in Japanese mythology. In other stories, the universe emanates from fundamental principles, such as Brahman and Prakrti, or the yin and yang of the Tao.
From the 6th century BCE, the pre-Socratic Greek philosophers developed the earliest known philosophical models of the universe. The earliest Greek philosophers noted that appearances can be deceiving, and sought to understand the underlying reality behind the appearances. In particular, they noted the ability of matter to change forms (e.g., ice to water to steam) and several philosophers proposed that all the apparently different materials of the world are different forms of a single primordial material, or arche. The first to do so was Thales, who proposed this material is Water. Thales' student, Anaximander, proposed that everything came from the limitless apeiron. Anaximenes proposed Air on account of its perceived attractive and repulsive qualities that cause the arche to condense or dissociate into different forms. Anaxagoras, proposed the principle of Nous (Mind). Heraclitus proposed fire (and spoke of logos). Empedocles proposed the elements: earth, wind, air and fire. His four element theory became very popular. Like Pythagoras, Plato believed that all things were composed of number, with the Empedocles' elements taking the form of the Platonic solids. Democritus, and later philosophers—most notably Leucippus—proposed that the universe was composed of indivisible atoms moving through void (vacuum). Aristotle did not believe that was feasible because air, like water, offers resistance to motion. Air will immediately rush in to fill a void, and moreover, without resistance, it would do so indefinitely fast.
Although Heraclitus argued for eternal change, his quasi-contemporary Parmenides made the radical suggestion that all change is an illusion, that the true underlying reality is eternally unchanging and of a single nature. Parmenides denoted this reality as (The One). Parmenides' theory seemed implausible to many Greeks, but his student Zeno of Elea challenged them with several famous paradoxes. Aristotle responded to these paradoxes by developing the notion of a potential countable infinity, as well as the infinitely divisible continuum. Unlike the eternal and unchanging cycles of time, he believed the world was bounded by the celestial spheres, and thus magnitude was only finitely multiplicative.
The Indian philosopher Kanada, founder of the Vaisheshika school, developed a theory of atomism and proposed that light and heat were varieties of the same substance. In the 5th century AD, the Buddhist atomist philosopher Dignāga proposed atoms to be point-sized, durationless, and made of energy. They denied the existence of substantial matter and proposed that movement consisted of momentary flashes of a stream of energy.
The theory of temporal finitism was inspired by the doctrine of Creation shared by the three Abrahamic religions: Judaism, Christianity and Islam. The Christian philosopher, John Philoponus, presented the philosophical arguments against the ancient Greek notion of an infinite past and future. Philoponus' arguments against an infinite past were used by the early Muslim philosopher, Al-Kindi (Alkindus); the Jewish philosopher, Saadia Gaon (Saadia ben Joseph); and the Muslim theologian, Al-Ghazali (Algazel). Borrowing from Aristotle's Physics and Metaphysics, they employed two logical arguments against an infinite past, the first being the "argument from the impossibility of the existence of an actual infinite", which states:
:"An actual infinite cannot exist." :"An infinite temporal regress of events is an actual infinite." :" An infinite temporal regress of events cannot exist."
The second argument, the "argument from the impossibility of completing an actual infinite by successive addition", states:
:"An actual infinite cannot be completed by successive addition." :"The temporal series of past events has been completed by successive addition." :" The temporal series of past events cannot be an actual infinite."
Both arguments were adopted by Christian philosophers and theologians, and the second argument in particular became more famous after it was adopted by Immanuel Kant in his thesis of the first antinomy concerning time.
Later Greek philosophers, observing the motions of the heavenly bodies, were concerned with developing models of the universe based more profoundly on empirical evidence. The first coherent model was proposed by Eudoxus of Cnidos. According to Aristotle's physical interpretation of the model, celestial spheres eternally rotate with uniform motion around a stationary Earth. Normal matter, is entirely contained within the terrestrial sphere. This model was also refined by Callippus and after concentric spheres were abandoned, it was brought into nearly perfect agreement with astronomical observations by Ptolemy. The success of such a model is largely due to the mathematical fact that any function (such as the position of a planet) can be decomposed into a set of circular functions (the Fourier modes). Other Greek scientists, such as the Pythagorean philosopher Philolaus postulated that at the center of the universe was a "central fire" around which the Earth, Sun, Moon and Planets revolved in uniform circular motion. The Greek astronomer Aristarchus of Samos was the first known individual to propose a heliocentric model of the universe. Though the original text has been lost, a reference in Archimedes' book The Sand Reckoner describes Aristarchus' heliocentric theory. Archimedes wrote: (translated into English)
You King Gelon are aware the 'universe' is the name given by most astronomers to the sphere the center of which is the center of the Earth, while its radius is equal to the straight line between the center of the Sun and the center of the Earth. This is the common account as you have heard from astronomers. But Aristarchus has brought out a book consisting of certain hypotheses, wherein it appears, as a consequence of the assumptions made, that the universe is many times greater than the 'universe' just mentioned. His hypotheses are that the fixed stars and the Sun remain unmoved, that the Earth revolves about the Sun on the circumference of a circle, the Sun lying in the middle of the orbit, and that the sphere of fixed stars, situated about the same center as the Sun, is so great that the circle in which he supposes the Earth to revolve bears such a proportion to the distance of the fixed stars as the center of the sphere bears to its surface.
Aristarchus thus believed the stars to be very far away, and saw this as the reason why there was no visible parallax, that is, an observed movement of the stars relative to each other as the Earth moved around the Sun. The stars are in fact much farther away than the distance that was generally assumed in ancient times, which is why stellar parallax is only detectable with telescopes. The geocentric model, consistent with planetary parallax, was assumed to be an explanation for the unobservability of the parallel phenomenon, stellar parallax. The rejection of the heliocentric view was apparently quite strong, as the following passage from Plutarch suggests (On the Apparent Face in the Orb of the Moon):
Cleanthes [a contemporary of Aristarchus and head of the Stoics] thought it was the duty of the Greeks to indict Aristarchus of Samos on the charge of impiety for putting in motion the Hearth of the universe [i.e. the earth], . . . supposing the heaven to remain at rest and the earth to revolve in an oblique circle, while it rotates, at the same time, about its own axis. [1]
The only other astronomer from antiquity known by name who supported Aristarchus' heliocentric model was Seleucus of Seleucia, a Hellenized Babylonian astronomer who lived a century after Aristarchus. According to Plutarch, Seleucus was the first to prove the heliocentric system through reasoning, but it is not known what arguments he used. Seleucus' arguments for a heliocentric theory were probably related to the phenomenon of tides. According to Strabo (1.1.9), Seleucus was the first to state that the tides are due to the attraction of the Moon, and that the height of the tides depends on the Moon's position relative to the Sun. Alternatively, he may have proved the heliocentric theory by determining the constants of a geometric model for the heliocentric theory and by developing methods to compute planetary positions using this model, like what Nicolaus Copernicus later did in the 16th century. During the Middle Ages, heliocentric models may have also been proposed by the Indian astronomer, Aryabhata, and by the Persian astronomers, Albumasar and Al-Sijzi.
The Aristotelian model was accepted in the Western world for roughly two millennia, until Copernicus revived Aristarchus' theory that the astronomical data could be explained more plausibly if the earth rotated on its axis and if the sun were placed at the center of the universe.
As noted by Copernicus himself, the suggestion that the Earth rotates was very old, dating at least to Philolaus (c. 450 BC), Heraclides Ponticus (c. 350 BC) and Ecphantus the Pythagorean. Roughly a century before Copernicus, Christian scholar Nicholas of Cusa also proposed that the Earth rotates on its axis in his book, On Learned Ignorance (1440). Aryabhata (476–550), Brahmagupta (598–668), Albumasar and Al-Sijzi, also proposed that the Earth rotates on its axis. The first empirical evidence for the Earth's rotation on its axis, using the phenomenon of comets, was given by Tusi (1201–1274) and Ali Qushji (1403–1474).
This cosmology was accepted by Isaac Newton, Christiaan Huygens and later scientists. Edmund Halley (1720) and Jean-Philippe de Cheseaux (1744) noted independently that the assumption of an infinite space filled uniformly with stars would lead to the prediction that the nighttime sky would be as bright as the sun itself; this became known as Olbers' paradox in the 19th century. Newton believed that an infinite space uniformly filled with matter would cause infinite forces and instabilities causing the matter to be crushed inwards under its own gravity. This instability was clarified in 1902 by the Jeans instability criterion. One solution to these paradoxes is the Charlier universe, in which the matter is arranged hierarchically (systems of orbiting bodies that are themselves orbiting in a larger system, ad infinitum) in a fractal way such that the universe has a negligibly small overall density; such a cosmological model had also been proposed earlier in 1761 by Johann Heinrich Lambert. A significant astronomical advance of the 18th century was the realization by Thomas Wright, Immanuel Kant and others of nebulae.
The modern era of physical cosmology began in 1917, when Albert Einstein first applied his general theory of relativity to model the structure and dynamics of the universe.
Of the four fundamental interactions, gravitation is dominant at cosmological length scales; that is, the other three forces are believed to play a negligible role in determining structures at the level of planets, stars, galaxies and larger-scale structures. Since all matter and energy gravitate, gravity's effects are cumulative; by contrast, the effects of positive and negative charges tend to cancel one another, making electromagnetism relatively insignificant on cosmological length scales. The remaining two interactions, the weak and strong nuclear forces, decline very rapidly with distance; their effects are confined mainly to sub-atomic length scales.
Given gravitation's predominance in shaping cosmological structures, accurate predictions of the universe's past and future require an accurate theory of gravitation. The best theory available is Albert Einstein's general theory of relativity, which has passed all experimental tests hitherto. However, since rigorous experiments have not been carried out on cosmological length scales, general relativity could conceivably be inaccurate. Nevertheless, its cosmological predictions appear to be consistent with observations, so there is no compelling reason to adopt another theory.
General relativity provides a set of ten nonlinear partial differential equations for the spacetime metric (Einstein's field equations) that must be solved from the distribution of mass-energy and momentum throughout the universe. Since these are unknown in exact detail, cosmological models have been based on the cosmological principle, which states that the universe is homogeneous and isotropic. In effect, this principle asserts that the gravitational effects of the various galaxies making up the universe are equivalent to those of a fine dust distributed uniformly throughout the universe with the same average density. The assumption of a uniform dust makes it easy to solve Einstein's field equations and predict the past and future of the universe on cosmological time scales.
Einstein's field equations include a cosmological constant (Λ), that corresponds to an energy density of empty space. Depending on its sign, the cosmological constant can either slow (negative Λ) or accelerate (positive Λ) the expansion of the universe. Although many scientists, including Einstein, had speculated that Λ was zero, recent astronomical observations of type Ia supernovae have detected a large amount of "dark energy" that is accelerating the universe's expansion. Preliminary studies suggest that this dark energy corresponds to a positive Λ, although alternative theories cannot be ruled out as yet. Russian physicist Zel'dovich suggested that Λ is a measure of the zero-point energy associated with virtual particles of quantum field theory, a pervasive vacuum energy that exists everywhere, even in empty space. Evidence for such zero-point energy is observed in the Casimir effect.
The universe has at least three spatial and one temporal (time) dimension. It was long thought that the spatial and temporal dimensions were different in nature and independent of one another. However, according to the special theory of relativity, spatial and temporal separations are interconvertible (within limits) by changing one's motion.
To understand this interconversion, it is helpful to consider the analogous interconversion of spatial separations along the three spatial dimensions. Consider the two endpoints of a rod of length L. The length can be determined from the differences in the three coordinates Δx, Δy and Δz of the two endpoints in a given reference frame
:
using the Pythagorean theorem. In a rotated reference frame, the coordinate differences differ, but they give the same length
:
Thus, the coordinates differences (Δx, Δy, Δz) and (Δξ, Δη, Δζ) are not intrinsic to the rod, but merely reflect the reference frame used to describe it; by contrast, the length L is an intrinsic property of the rod. The coordinate differences can be changed without affecting the rod, by rotating one's reference frame.
The analogy in spacetime is called the interval between two events; an event is defined as a point in spacetime, a specific position in space and a specific moment in time. The spacetime interval between two events is given by
:
where c is the speed of light. According to special relativity, one can change a spatial and time separation (L1, Δt1) into another (L2, Δt2) by changing one's reference frame, as long as the change maintains the spacetime interval s. Such a change in reference frame corresponds to changing one's motion; in a moving frame, lengths and times are different from their counterparts in a stationary reference frame. The precise manner in which the coordinate and time differences change with motion is described by the Lorentz transformation.
The distances between the spinning galaxies increase with time, but the distances between the stars within each galaxy stay roughly the same, due to their gravitational interactions. This animation illustrates a closed Friedmann universe with zero cosmological constant Λ; such a universe oscillates between a Big Bang and a Big Crunch.
In non-Cartesian (non-square) or curved coordinate systems, the Pythagorean theorem holds only on infinitesimal length scales and must be augmented with a more general metric tensor gμν, which can vary from place to place and which describes the local geometry in the particular coordinate system. However, assuming the cosmological principle that the universe is homogeneous and isotropic everywhere, every point in space is like every other point; hence, the metric tensor must be the same everywhere. That leads to a single form for the metric tensor, called the Friedmann-Lemaître-Robertson-Walker metric
:
where (r, θ, φ) correspond to a spherical coordinate system. This metric has only two undetermined parameters: an overall length scale R that can vary with time, and a curvature index k that can be only 0, 1 or −1, corresponding to flat Euclidean geometry, or spaces of positive or negative curvature. In cosmology, solving for the history of the universe is done by calculating R as a function of time, given k and the value of the cosmological constant Λ, which is a (small) parameter in Einstein's field equations. The equation describing how R varies with time is known as the Friedmann equation, after its inventor, Alexander Friedmann.
The solutions for R(t) depend on k and Λ, but some qualitative features of such solutions are general. First and most importantly, the length scale R of the universe can remain constant only if the universe is perfectly isotropic with positive curvature (k=1) and has one precise value of density everywhere, as first noted by Albert Einstein. However, this equilibrium is unstable and since the universe is known to be inhomogeneous on smaller scales, R must change, according to general relativity. When R changes, all the spatial distances in the universe change in tandem; there is an overall expansion or contraction of space itself. This accounts for the observation that galaxies appear to be flying apart; the space between them is stretching. The stretching of space also accounts for the apparent paradox that two galaxies can be 40 billion light years apart, although they started from the same point 13.7 billion years ago and never moved faster than the speed of light.
Second, all solutions suggest that there was a gravitational singularity in the past, when R goes to zero and matter and energy became infinitely dense. It may seem that this conclusion is uncertain since it is based on the questionable assumptions of perfect homogeneity and isotropy (the cosmological principle) and that only the gravitational interaction is significant. However, the Penrose-Hawking singularity theorems show that a singularity should exist for very general conditions. Hence, according to Einstein's field equations, R grew rapidly from an unimaginably hot, dense state that existed immediately following this singularity (when R had a small, finite value); this is the essence of the Big Bang model of the universe. A common misconception is that the Big Bang model predicts that matter and energy exploded from a single point in space and time; that is false. Rather, space itself was created in the Big Bang and imbued with a fixed amount of energy and matter distributed uniformly throughout; as space expands (i.e., as R(t) increases), the density of that matter and energy decreases.
Third, the curvature index k determines the sign of the mean spatial curvature of spacetime averaged over length scales greater than a billion light years. If k=1, the curvature is positive and the universe has a finite volume. Such universes are often visualized as a three-dimensional sphere S3 embedded in a four-dimensional space. Conversely, if k is zero or negative, the universe may have infinite volume, depending on its overall topology. It may seem counter-intuitive that an infinite and yet infinitely dense universe could be created in a single instant at the Big Bang when R=0, but exactly that is predicted mathematically when k does not equal 1. For comparison, an infinite plane has zero curvature but infinite area, whereas an infinite cylinder is finite in one direction and a torus is finite in both. A toroidal universe could behave like a normal universe with periodic boundary conditions, as seen in "wrap-around" video games such as Asteroids; a traveler crossing an outer "boundary" of space going outwards would reappear instantly at another point on the boundary moving inwards.
The ultimate fate of the universe is still unknown, because it depends critically on the curvature index k and the cosmological constant Λ. If the universe is sufficiently dense, k equals +1, meaning that its average curvature throughout is positive and the universe will eventually recollapse in a Big Crunch, possibly starting a new universe in a Big Bounce. Conversely, if the universe is insufficiently dense, k equals 0 or −1 and the universe will expand forever, cooling off and eventually becoming inhospitable for all life, as the stars die and all matter coalesces into black holes (the Big Freeze and the heat death of the universe). As noted above, recent data suggests that the expansion speed of the universe is not decreasing as originally expected, but increasing; if this continues indefinitely, the universe will eventually rip itself to shreds (the Big Rip). Experimentally, the universe has an overall density that is very close to the critical value between recollapse and eternal expansion; more careful astronomical observations are needed to resolve the question.
The prevailing Big Bang model accounts for many of the experimental observations described above, such as the correlation of distance and redshift of galaxies, the universal ratio of hydrogen:helium atoms, and the ubiquitous, isotropic microwave radiation background. As noted above, the redshift arises from the metric expansion of space; as the space itself expands, the wavelength of a photon traveling through space likewise increases, decreasing its energy. The longer a photon has been traveling, the more expansion it has undergone; hence, older photons from more distant galaxies are the most red-shifted. Determining the correlation between distance and redshift is an important problem in experimental physical cosmology.
Other experimental observations can be explained by combining the overall expansion of space with nuclear and atomic physics. As the universe expands, the energy density of the electromagnetic radiation decreases more quickly than does that of matter, since the energy of a photon decreases with its wavelength. Thus, although the energy density of the universe is now dominated by matter, it was once dominated by radiation; poetically speaking, all was light. As the universe expanded, its energy density decreased and it became cooler; as it did so, the elementary particles of matter could associate stably into ever larger combinations. Thus, in the early part of the matter-dominated era, stable protons and neutrons formed, which then associated into atomic nuclei. At this stage, the matter in the universe was mainly a hot, dense plasma of negative electrons, neutral neutrinos and positive nuclei. Nuclear reactions among the nuclei led to the present abundances of the lighter nuclei, particularly hydrogen, deuterium, and helium. Eventually, the electrons and nuclei combined to form stable atoms, which are transparent to most wavelengths of radiation; at this point, the radiation decoupled from the matter, forming the ubiquitous, isotropic background of microwave radiation observed today.
Other observations are not answered definitively by known physics. According to the prevailing theory, a slight imbalance of matter over antimatter was present in the universe's creation, or developed very shortly thereafter, possibly due to the CP violation that has been observed by particle physicists. Although the matter and antimatter mostly annihilated one another, producing photons, a small residue of matter survived, giving the present matter-dominated universe. Several lines of evidence also suggest that a rapid cosmic inflation of the universe occurred very early in its history (roughly 10−35 seconds after its creation). Recent observations also suggest that the cosmological constant (Λ) is not zero and that the net mass-energy content of the universe is dominated by a dark energy and dark matter that have not been characterized scientifically. They differ in their gravitational effects. Dark matter gravitates as ordinary matter does, and thus slows the expansion of the universe; by contrast, dark energy serves to accelerate the universe's expansion.
Some speculative theories have proposed that this universe is but one of a set of disconnected universes, collectively denoted as the multiverse, challenging or enhancing more limited definitions of the universe. Scientific multiverse theories are distinct from concepts such as alternate planes of consciousness and simulated reality, although the idea of a larger universe is not new; for example, Bishop Étienne Tempier of Paris ruled in 1277 that God could create as many universes as he saw fit, a question that was being hotly debated by the French theologians.
Max Tegmark developed a four part classification scheme for the different types of multiverses that scientists have suggested in various problem domains. An example of such a theory is the chaotic inflation model of the early universe. Another is the many-worlds interpretation of quantum mechanics. Parallel worlds are generated in a manner similar to quantum superposition and decoherence, with all states of the wave function being realized in separate worlds. Effectively, the multiverse evolves as a universal wavefunction. If the big bang that created our mutliverse created an ensemble of multiverses, the wave function of the ensemble would be entangled in this sense.
The least controversial category of multiverse in Tegmark's scheme is Level I, which describes distant space-time events "in our own universe". If space is infinite, or sufficiently large and uniform, identical instances of the history of Earth's entire Hubble volume occur every so often, simply by chance. Tegmark calculated our nearest so-called doppelgänger, is 1010115 meters away from us (a double exponential function larger than a googolplex). In principle, it would be impossible to scientifically verify an identical Hubble volume. However, it does follow as a fairly straightforward consequence from otherwise unrelated scientific observations and theories. Tegmark suggests that statistical analysis exploiting the anthropic principle provides an opportunity to test multiverse theories in some cases. Generally, science would consider a multiverse theory that posits neither a common point of causation, nor the possibility of interaction between universes, to be an ideal speculation.
The shape or geometry of the universe includes both local geometry in the observable universe and global geometry, which we may or may not be able to measure. Shape can refer to curvature and topology. More formally, the subject in practice investigates which 3-manifold corresponds to the spatial section in comoving coordinates of the four-dimensional space-time of the universe. Cosmologists normally work with a given space-like slice of spacetime called the comoving coordinates. In terms of observation, the section of spacetime that can be observed is the backward light cone (points within the cosmic light horizon, given time to reach a given observer). If the observable universe is smaller than the entire universe (in some models it is many orders of magnitude smaller), one cannot determine the global structure by observation: one is limited to a small patch.
Among the Friedmann–Lemaître–Robertson–Walker (FLRW) models, the presently most popular shape of the Universe found to fit observational data according to cosmologists is the infinite flat model, while other FLRW models include the Poincaré dodecahedral space and the Picard horn. The data fit by these FLRW models of space especially include the Wilkinson Microwave Anisotropy Probe (WMAP) maps of cosmic background radiation. NASA released the first WMAP cosmic background radiation data in February 2003. In 2009 the Planck observatory was launched to observe the microwave background at higher resolution than WMAP, possibly providing more information on the shape of the Universe. The data should be released in late 2012.

Monty Python (sometimes known as The Pythons) was a British surreal comedy group who created their influential Monty Python's Flying Circus, a British television comedy sketch show that first aired on the BBC on 5 October 1969. Forty-five episodes were made over four series. The Python phenomenon developed from the television series into something larger in scope and impact, spawning touring stage shows, films, numerous albums, several books and a stage musical as well as launching the members to individual stardom. The group's influence on comedy has been compared to Elvis Presley's influence on music.
The television series, broadcast by the BBC from 1969 to 1974, was conceived, written and performed by members Graham Chapman, John Cleese, Terry Gilliam, Eric Idle, Terry Jones, and Michael Palin. Loosely structured as a sketch show, but with an innovative stream-of-consciousness approach (aided by Gilliam's animation), it pushed the boundaries of what was acceptable in style and content. A self-contained comedy team responsible for both writing and performing their work, they changed the way performers entertained audiences. The Pythons' creative control allowed them to experiment with form and content, discarding rules of television comedy. Their influence on British comedy has been apparent for years, while in North America it has coloured the work of cult performers from the early editions of Saturday Night Live through to more recent absurdist trends in television comedy. "Pythonesque" has entered the English lexicon as a result.
In a 2005 UK poll to find The Comedian's Comedian, three of the six Pythons members were voted by fellow comedians and comedy insiders to be among the top 50 greatest comedians ever: Cleese at #2, Idle at #21, and Palin at #30.
Python members appeared in and/or wrote the following shows before Monty Python's Flying Circus. The Frost Report is credited as first uniting the British Pythons and providing an environment in which they could develop their particular styles:
Several featured other important British comedy writers or performers of the future, including Marty Feldman, Jonathan Lynn, David Jason and David Frost, as well as members of other future comedy teams, Ronnie Corbett and Ronnie Barker (the Two Ronnies), and Tim Brooke-Taylor, Graeme Garden and Bill Oddie (the Goodies).
Following the success of Do Not Adjust Your Set, originally intended to be a children's programme, with adults, ITV offered Palin, Jones, Idle and Gilliam their own series together. At the same time Cleese and Chapman were offered a show by the BBC, which had been impressed by their work on The Frost Report and At Last The 1948 Show. Cleese was reluctant to do a two-man show for various reasons, including Chapman's supposedly difficult personality. Cleese had fond memories of working with Palin and invited him to join the team. With the ITV series still in pre-production, Palin agreed and suggested the involvement of his writing partner Jones and colleague Idle—who in turn suggested that Gilliam could provide animations for the projected series. Much has been made of the fact that the Monty Python troupe is the result of Cleese's desire to work with Palin and the chance circumstances that brought the other four members into the fold.
After much debate, Jones remembered an animation Gilliam had created for Do Not Adjust Your Set called Beware of the Elephants, which had intrigued him with its stream-of-consciousness style. Jones felt it would be a good concept to apply to the series: allowing sketches to blend into one another. Palin had been equally fascinated by another of Gilliam's efforts, entitled Christmas Cards, and agreed that it represented "a way of doing things differently". Since Cleese, Chapman and Idle were less concerned with the overall flow of the programme, it was Jones, Palin and Gilliam who became largely responsible for the presentation style of the Flying Circus series, in which disparate sketches are linked to give each episode the appearance of a single stream-of-consciousness (often using a Gilliam animation to move from the closing image of one sketch to the opening scene of another).
Writing started at 9 am and finished at 5 pm. Typically, Cleese and Chapman worked as one pair isolated from the others, as did Jones and Palin, while Idle wrote alone. After a few days, they would join together with Gilliam, critique their scripts, and exchange ideas. Their approach to writing was democratic. If the majority found an idea humorous, it was included in the show. The casting of roles for the sketches was a similarly unselfish process, since each member viewed himself primarily as a 'writer', rather than an actor desperate for screen time. When the themes for sketches were chosen, Gilliam had carte blanche to decide how to bridge them with animations, using a camera, scissors, and airbrush.
While the show was a collaborative process, different factions within Python were responsible for elements of the team's humour. In general, the work of the Oxford-educated members was more visual, and more fanciful conceptually (e.g., the arrival of the Spanish Inquisition in a suburban front room), while the Cambridge graduates' sketches tended to be more verbal and more aggressive (for example, Cleese and Chapman's many "confrontation" sketches, where one character intimidates or hurls abuse, or Idle's characters with bizarre verbal quirks, such as The Man Who Speaks In Anagrams). Cleese confirmed that "most of the sketches with heavy abuse were Graham's and mine, anything that started with a slow pan across countryside and impressive music was Mike and Terry's, and anything that got utterly involved with words and disappeared up any personal orifice was Eric's". Gilliam's animations, meanwhile, ranged from the whimsical to the savage (the cartoon format allowing him to create some astonishingly violent scenes without fear of censorship).
Several names for the show were considered before Monty Python's Flying Circus was settled upon. Some were Owl Stretching Time, Toad Elevating Moment, A Bucket, a Horse and a Spoon, Vaseline Review and Bun, Wackett, Buzzard, Stubble and Boot. Flying Circus stuck when the BBC explained it had printed that name in its schedules and was not prepared to amend it. Many variations on the name in front of this title then came and went (popular legend holds that the BBC considered Monty Python's Flying Circus to be a ridiculous name, at which point the group threatened to change their name every week until the BBC relented). "Gwen Dibley's Flying Circus" was named after a woman Palin had read about in the newspaper, thinking it would be amusing if she were to discover she had her own TV show. "Baron Von Took's Flying Circus" was considered as an affectionate tribute to Barry Took, the man who had brought them together. Arthur Megapode's Flying Circus was suggested, then discarded.
There are differing, somewhat confusing accounts of the origins of the Python name although the members agree that its only "significance" was that they thought it sounded funny. In the 1998 documentary Live At Aspen during the US Comedy Arts Festival, where the troupe was awarded the AFI Star Award by the American Film Institute, the group implied that "Monty" was selected (Eric Idle's idea) as a gently-mocking tribute to Field Marshal Lord Montgomery, a legendary British general of World War II; requiring a "slippery-sounding" surname, they settled on "Python". On other occasions Idle has claimed that the name "Monty" was that of a popular and rotund fellow who drank in his local pub; people would often walk in and ask the barman, "Has Monty been in yet?", forcing the name to become stuck in his mind. The name Monty Python was later described by the BBC as being "envisaged by the team as the perfect name for a sleazy entertainment agent".
The Python theme music is The Liberty Bell, a march by John Philip Sousa, which was chosen, among other reasons, because the recording was in the public domain.
The use of Gilliam's surreal, collage stop motion animations was another innovative intertextual element of the Python style. Many of the images Gilliam used were lifted from famous works of art, and from Victorian illustrations and engravings. The giant foot which crushes the show's title at the end of the opening credits is in fact the foot of Cupid, cut from a reproduction of the Renaissance masterpiece Venus, Cupid, Folly, and Time by Bronzino. This foot, and Gilliam's style in general, are visual trademarks of the series.
The Pythons used the British tradition of cross-dressing comedy by donning frocks and makeup and playing female roles themselves while speaking in falsetto. Generally speaking, female roles were played by a woman (usually Carol Cleveland) when the scene specifically required that the character be sexually attractive (although sometimes they used Idle for this). In some episodes and later in Monty Python's Life of Brian they took the idea one step further by playing women who impersonated men (in the stoning scene).
Many sketches are well-known and widely quoted. "Dead Parrot", "The Lumberjack Song", "Spam", "Nudge Nudge", "The Spanish Inquisition", "Upper Class Twit of the Year", "Cheese Shop" and "The Ministry of Silly Walks" are just a few examples.
The rest of the group carried on for one more "half" series before calling a halt to the programme in 1974. The name Monty Python's Flying Circus appears in the opening animation for series four, but in the end credits the show is listed as simply "Monty Python". Despite his official departure from the group, Cleese supposedly made a (non-speaking) cameo appearance in the fourth series, but never appeared in the credits as a performer. Several episodes credit him as a co-writer since some sketches were recycled from scenes cut from the Holy Grail script. While the first three series contained 13 episodes each, the fourth ended after six.
Time-Life Films had the right to distribute all BBC-TV programs in America, however they had decided that British comedy simply would not work in the U.S.A. Therefore, it was not worth the investment to convert the Python shows from the European PAL standard to the American NTSC standard, which meant PBS stations could not afford the programmes. Finally, in 1974, Greg Garrison, TV producer for Dean Martin, used a couple of Python sketches ("Bicycle Repairman" and "The Dull Life of a Stockbroker") on the NBC series ComedyWorld, a summer replacement series for The Dean Martin Show. Payment for use of these segments was enough to pay for the conversion of the entire Python library to NTSC standard. At last, they could be sold to non-commercial TV stations, where officially they began airing in October 1974—exactly 5 years after their BBC debut. One PBS station had a program director (Ron Devillier) so eager that he 'jumped the gun' and started broadcasting the 'Flying Circus' episodes in that summer on the unlikely KERA in Dallas. The ratings shot through the roof—and was an encouraging sign to the other 100 stations that had signed up to air the shows. There was also cross-promotion from FM radio stations across the country, whose airing of tracks from the Python LPs had already introduced American audiences to this bizarre brand of comedy.
With the popularity of Python throughout the rest of the 1970s and through most of the 1980s, PBS stations looked at other British comedies, leading to UK shows such as Are You Being Served? gaining a US audience, and leading, over time, to many PBS stations having a "British Comedy Night" which airs many popular UK comedies.
The backers of the film wanted to cut the famous Black Knight scene (in which the Black Knight loses his limbs in a duel) but it was eventually kept in the movie.
The focus therefore shifted to a separate individual born at the same time, in a neighbouring stable. When Jesus appears in the film (first, as a baby in the stable, and then later on the Mount, speaking the Beatitudes), he is played straight (by actor Kenneth Colley) and portrayed with respect. The comedy begins when members of the crowd mishear his statements of peace, love and tolerance. ("I think he said, 'Blessed are the cheesemakers.'")
Directing duties were handled solely by Jones, having amicably agreed with Gilliam that Jones' approach to film-making was better suited for Python's general performing style. Holy Grail's production had often been stilted by their differences behind the camera. Gilliam again contributed two animated sequences (one being the opening credits) and took charge of set design. The film was shot on location in Tunisia, the finances being provided this time by former Beatle George Harrison, who together with Denis O'Brien formed the production company Hand-Made Films for the movie. He had a cameo role as the 'owner of the Mount.'
Despite its subject matter attracting controversy, particularly upon its initial release, it has (together with its predecessor) been ranked among the greatest comedy films. A Channel 4 poll in 2005 ranked Holy Grail in sixth place, with Life of Brian at the top.
Python's final film returned to something structurally closer to the style of Flying Circus. A series of sketches loosely follows the ages of man from birth to death. Directed again by Jones solo, The Meaning of Life is embellished with some of Python's most bizarre and disturbing moments, as well as various elaborate musical numbers. The film is by far their darkest work, containing a great deal of black humour, garnished by some spectacular violence (including an operation to remove a liver from a living patient without anaesthetic and the morbidly obese Mr. Creosote exploding over several restaurant patrons). At the time of its release, the Pythons confessed their aim was to offend "absolutely everyone."
Besides the opening credits and the fish sequence, Gilliam, by now an established live action director, no longer wanted to produce any linking cartoons, offering instead to direct one sketch—The Crimson Permanent Assurance. Under his helm, though, the segment grew so ambitious and tangential that it was cut from the movie and used as a supporting feature in its own right. (Television screenings also use it as a prologue.) Crucially, this was the last project that all six Pythons would collaborate on, except for the 1989 compilation Parrot Sketch Not Included, where they are all seen sitting in a closet for four seconds. This would be the last time Chapman appeared on-screen with the Pythons.
Cleese and Jones had an involvement (as performer, writer or director) in all four Amnesty benefit shows, Palin in three, Chapman in two and Gilliam in one. Idle did not participate in the Amnesty shows. Notwithstanding Idle's lack of participation, the other five members (together with "Associate Pythons" Carol Cleveland and Neil Innes) all appeared together in the first Secret Policeman's Ball benefit—the 1976 A Poke In The Eye (With A Sharp Stick)—where they performed several Python sketches. In this first show they were collectively billed as Monty Python. (Peter Cook deputised for the errant Idle in one major sketch The Courtroom.) In the next three shows, the participating Python members performed many Python sketches, but were billed under their individual names rather than under the collective Python banner. After a six-year break, Amnesty resumed producing Secret Policeman's Ball benefit shows in 1987 (sometimes with, and sometimes without variants of the iconic title) and by 2006 had presented a total of twelve such shows. The shows since 1987 have featured newer generations of British comedic performers, including many who have attributed their participation in the show to their desire to emulate the Python's pioneering work for Amnesty. (Cleese and Palin made a brief cameo appearance in the 1989 Amnesty show; apart from that the Pythons have not appeared in shows after the first four.)
Palin and Jones wrote the comedic TV series Ripping Yarns (1976–79), starring Palin. Jones also appeared in the pilot episode and Cleese appeared in a non-speaking part in the episode "Golden Gordon". Jones' film Erik the Viking, also has Cleese playing a small part.
In 1996, Terry Jones wrote and directed an adaption of Kenneth Grahame's novel The Wind in the Willows. It featured four members of Monty Python: Jones as Mr. Toad, Idle as Ratty, Cleese as Mr. Toad's lawyer, and Palin as the Sun. Gilliam was considered for the voice of the river.
In terms of numbers of productions, Cleese has the most prolific solo career, having appeared in 59 theatrical films, 22 TV shows or series (including Cheers, 3rd Rock from the Sun, Q's assistant in the James Bond movies, and Will & Grace), 23 direct-to-video productions, six video games, and a number of commercials. His BBC sitcom Fawlty Towers (written by and starring Cleese together with his then-wife Connie Booth), is considered the greatest solo work by a Python since the sketch show finished. It is the only comedy series to rank higher than the Flying Circus on the BFI TV 100's list, topping the whole poll.
Idle enjoyed critical success with Rutland Weekend Television in the mid-1970s, out of which came the Beatles parody The Rutles (responsible for the cult mockumentary All You Need Is Cash), and as an actor in Nuns on the Run (1990) with Robbie Coltrane. Idle has had success with Python songs: "Always Look on the Bright Side of Life" went to no. 3 in the UK singles chart in 1991. The song had been revived by Simon Mayo on BBC Radio 1, and was consequently released as a single that year. The theatrical phenomenon of the Python musical Spamalot has made Idle the most financially successful of the troupe post-Python. Written by Idle, it has proved an enormous hit on Broadway, London's West End and also Las Vegas. This was followed by Not the Messiah (He's a Very Naughty Boy), which repurposes The Life of Brian as an oratorio. For the work's 2007 premiere at the Luminato festival in Toronto (which commissioned the work), Idle himself sang the "baritone-ish" part.
In 1996, Jones, Idle, Cleese and Palin were featured in a film adaptation of The Wind in the Willows, which was later renamed Mr. Toad's Wild Ride.
In 1998 during the US Comedy Arts Festival, where the troupe was awarded the AFI Star Award by the American Film Institute, the five remaining members along with what was purported to be Chapman's ashes, were reunited on stage for the first time in 18 years. The occasion was in the form of an interview called Monty Python Live At Aspen, (hosted by Robert Klein, with an appearance by Eddie Izzard) in which the team looked back at some of their work and performed a few new sketches.
On 9 October 1999, to commemorate 30 years since the first Flying Circus television broadcast, BBC2 devoted an evening to Python programmes, including a documentary charting the history of the team, interspersed with new sketches by the Monty Python team filmed especially for the event. The program appears, though omitting a few things, on the DVD The Life of Python. Though Idle's involvement in the special is limited, the final sketch marks the only time since 1989 that all surviving members of the troupe appear in one sketch, albeit not in the same room.
In 2002, four of the surviving members, bar Cleese, performed "The Lumberjack Song" and "Sit on My Face" for George Harrison's memorial concert. The reunion also included regular supporting contributors Neil Innes and Carol Cleveland, with a special appearance from Tom Hanks.
In an interview to publicise the DVD release of The Meaning of Life, Cleese said a further reunion was unlikely. "It is absolutely impossible to get even a majority of us together in a room, and I'm not joking," Cleese said. He said that the problem was one of business rather than one of bad feelings. A sketch appears on the same DVD spoofing the impossibility of a full reunion, bringing the members “together” in a deliberately unconvincing fashion with modern bluescreen/greenscreen techniques.
Idle has responded to queries about a Python reunion by adapting a line used by George Harrison in response to queries about a possible Beatles reunion. When asked in November 1989 about such a possibility, Harrison responded: "As far as I'm concerned, there won't be a Beatles reunion as long as John Lennon remains dead." Idle's version of this was that he expected to see a proper Python reunion, "just as soon as Graham Chapman comes back from the dead", but added, "we're talking to his agent about terms."
2003's The Pythons Autobiography By The Pythons, compiled from interviews with the surviving members, reveals that a series of disputes in 1998, over a possible sequel to Holy Grail that had been conceived by Idle, may have resulted in the group's permanent fission. Cleese's feeling was that The Meaning of Life had been personally difficult and ultimately mediocre, and did not wish to be involved in another Python project for a variety of reasons (not least amongst them was the absence of Chapman, whose straight man-like central roles in the original Grail and Brian films had been considered to be essential performance anchorage). Apparently Idle was angry with Cleese for refusing to do the film, which most of the remaining Pythons thought reasonably promising (the basic plot would have taken on a self-referential tone, featuring them in their main 'knight' guises from Holy Grail, mulling over the possibilities of reforming their posse). The book also reveals that a secondary option around this point was the possibility of revitalising the Python brand with a new stage tour, perhaps with the promise of new material. This idea had also hit the buffers at Cleese's refusal, this time with the backing of other members.
March 2005 saw a full, if non-performing, reunion of the surviving cast members at the premiere of Idle's musical Spamalot, based on Monty Python and the Holy Grail. It opened in Chicago and has since played in New York on Broadway, London and numerous other major cities across the world. In 2004, it was nominated for 14 Tony Awards and won three: Best Musical, Best Direction of a Musical for Mike Nichols and Best Performance by a Featured Actress in a Musical for Sara Ramirez, who played the Lady of the Lake, a character specially added for the musical. Cleese played the voice of God, played in the film by Chapman.
Owing in part to the success of Spamalot, PBS announced on 13 July 2005, that it would begin to re-air the entire run of Monty Python's Flying Circus and new one-hour specials focusing on each member of the group, called Monty Python's Personal Best. Each episode was written and produced by the individual being honoured, with the five remaining Pythons collaborating on Chapman's programme, the only one of the editions to take on a serious tone with its new material.
Eric Idle and John Cleese appeared on stage together singing "Always Look on the Bright Side of Life" with the rest of the performers for the climax of Prince Charles 60th Birthday Show.
In 2009, to commemorate the fortieth anniversary of the first episode of Monty Python's Flying Circus, a six part documentary entitled Monty Python: Almost the Truth (The Lawyer's Cut) was released, featuring interviews with the surviving members of the team as well as archive interviews with Graham Chapman and numerous excerpts from the television series and films.
Also in commemoration of the 40th anniversary Idle, Palin, Jones and Gilliam appeared in a production of Not the Messiah (He's a Very Naughty Boy) at the Royal Albert Hall. The European premiere was held on 23 October 2009. An official 40th anniversary Monty Python reunion event took place in New York City on 15 October 2009 where the Team received a Special Award from the British Academy of Film and Television Arts.
In June 2011, it was announced that Monty Python have begun production on their first film project since the Meaning of Life in 1983. Their next film, A Liar's Autobiography, is an animated 3D movie based on the memoir of the late Python member, Graham Chapman, who died in 1989 at the age of 48. A Liar’s Autobiography was published in 1980 and details Chapman's journey through medical school, alcoholism, acknowledgement of his gay identity and the toils of surreal comedy.
Asked what was true in a deliberately fanciful account by Chapman of his life, Terry Jones joked: "Nothing . . . it’s all a downright, absolute, blackguardly lie."
The film will use Chapman's own voice - from a reading of his autobiography shortly before he died of cancer - and entertainment channel EPIX announced that the film will be released in early 2012 in both 2D and 3D formats. Produced and directed by London-based Bill Jones, Ben Timlett and Jeff Simpson, the new film has 15 animation companies working on chapters that will range from three to 12 minutes in length, each in a different style.
John Cleese has recorded new dialogue which will be matched with Chapman’s voice and Michael Palin will voice Chapman’s mother and father. Terry Gilliam plays various roles. Among the original Python group, only Eric Idle has not become involved, though Timlett said the filmmakers are “working on” him.
John Cleese is the oldest Python. He met his future Python writing partner, Graham Chapman in Cambridge.
Terry Gilliam, an American, was the only member of the troupe of non-British origin. He started off as an animator and strip cartoonist for Harvey Kurtzman's Help! magazine, one issue of which featured Cleese. Moving from the USA to England, he animated features for Do Not Adjust Your Set and was then asked by its makers to join them on their next project: Monty Python's Flying Circus. He co-directed Monty Python and the Holy Grail and directed short segments of other Python films (for instance "The Crimson Permanent Assurance", the short film that appears before The Meaning of Life).
When Monty Python was first formed, two writing partnerships were already in place: Cleese and Chapman, Jones and Palin. That left two in their own corners: Gilliam, operating solo due to the nature of his work, and Eric Idle. Regular themes in his contributions were elaborate wordplay and musical numbers. After Flying Circus, he hosted Saturday Night Live four times in the first five seasons. Idle's initially successful solo career faltered in the 1990s with the failures of his 1993 film Splitting Heirs (written, produced by and starring him) and 1998's An Alan Smithee Film: Burn Hollywood Burn (in which he starred), which was awarded five Razzies, including 'Worst Picture of the Year'. He revived his career by returning to the source of his worldwide fame, adapting Monty Python material for other media. He also wrote the Broadway musical Spamalot, based on the Holy Grail movie. He also wrote Not the Messiah (He's a Very Naughty Boy), an oratorio derived from the Life of Brian.
Terry Jones has been described by other members of the team as the “heart” of the operation. Jones had a lead role in maintaining the group's unity and creative independence. Python biographer George Perry has commented that should you "speak to him on subjects as diverse as fossil fuels, or Rupert Bear, or mercenaries in the Middle Ages or Modern China... in a moment you will find yourself hopelessly out of your depth, floored by his knowledge." Many others agree that Jones is characterised by his irrepressible, good-natured enthusiasm. However, Jones' passion often led to prolonged arguments with other group members—in particular Cleese—with Jones often unwilling to back down. Since his major contributions were largely behind the scenes (direction, writing), and he often deferred to the other members of the group as an actor, Jones' importance to Python was often underrated. However, he does have the legacy of delivering possibly the most famous line in all of Python, as Brian's mother Mandy in Life of Brian, "He's not the Messiah, he's a very naughty boy!", a line voted the funniest in film history on two occasions.
Michael Palin attended Oxford, where he met his Python writing partner Jones. The two also wrote the series Ripping Yarns together. Palin and Jones originally wrote face-to-face, but soon found it was more productive to write apart and then come together to review what the other had written. Therefore, Jones and Palin's sketches tended to be more focused than that of the others, taking one bizarre situation, sticking to it, and building on it. After Flying Circus, he hosted Saturday Night Live four times in the first ten seasons. His comedy output began to decrease in amount following the increasing success of his travel documentaries for the BBC. Palin released a book of diaries from the Python years entitled Michael Palin Diaries 1969–1979, published in 2007.
Carol Cleveland was the most important female performer in the Monty Python ensemble, commonly referred to as the "Python Girl." Originally hired by producer/director John Howard Davies for just the first five episodes of the Flying Circus, she went on to appear in approximately two-thirds of the episodes as well as in all of the Python films, and in most of their stage shows as well. Her common portrayal as the stereotypical "blonde bimbo" eventually earned her the sobriquet "Carol Cleavage" from the other Pythons, but she felt that the variety of her roles should not be described in such a pejorative way.
Douglas Adams was "discovered" by Chapman when a version of the Footlights Revue (a 1974 BBC2 television show featuring some of Adams' early work) was performed live in London's West End. In Cleese's absence from the final TV series, the two formed a brief writing partnership, with Adams earning a writing credit in one episode for a sketch called "Patient Abuse". In the sketch, a man who had been stabbed by a nurse arrives at his doctor's office bleeding profusely from the stomach, when the doctor makes him fill out numerous senseless forms before he can administer treatment. He also had two cameo appearances in this season. Firstly, in the episode The Light Entertainment War, Adams shows up in a surgeon's mask (as Dr. Emile Koning, according to the on-screen captions), pulling on gloves, while Palin narrates a sketch that introduces one person after another, and never actually gets started. Secondly, at the beginning of Mr. Neutron, Adams is dressed in a "pepperpot" outfit and loads a missile onto a cart being driven by Terry Jones, who is calling out for scrap metal ("Any old iron..."). Adams and Chapman also subsequently attempted a few non-Python projects, including Out of the Trees. He also contributed to a sketch on the soundtrack album for Monty Python and the Holy Grail.
Stand-up comedian Eddie Izzard, a devoted fan of the group, has occasionally stood in for absent members. When the BBC held a "Python Night" in 1999 to celebrate 30 years of the first broadcast of Flying Circus, the Pythons recorded some new material with Izzard standing in for Idle, who had declined to partake in person (he taped a solo contribution from the US). Izzard hosted a history of the group entitled The Life of Python (1999) that was part of the Python Night and appeared with them at a festival/tribute in Aspen, Colorado, in 1998 (released on DVD as Live at Aspen).
The term has been applied to animations similar to those constructed by Gilliam (e.g. the cut-out style of South Park, whose creators have often acknowledged a debt to Python, including contributing material to the aforementioned 30th anniversary theme night).
Good Eats creator Alton Brown cited Python as one of the influences that shaped how he created the series, as well as how he authors the script for each episode. Recent episodes even include Gilliam-style animations to illustrate key points.

Stephen William Hawking, CH, CBE, FRS, FRSA (born 8 January 1942) is a British theoretical physicist and cosmologist, whose scientific books and public appearances have made him an academic celebrity. He is an Honorary Fellow of the Royal Society of Arts, a lifetime member of the Pontifical Academy of Sciences, and in 2009 was awarded the Presidential Medal of Freedom, the highest civilian award in the United States.
Hawking was the Lucasian Professor of Mathematics at the University of Cambridge for 30 years, taking up the post in 1979 and retiring on 1 October 2009. He is now Director of Research at the Centre for Theoretical Cosmology in the Department of Applied Mathematics and Theoretical Physics at the University of Cambridge. He is also a Fellow of Gonville and Caius College, Cambridge and a Distinguished Research Chair at the Perimeter Institute for Theoretical Physics in Waterloo, Ontario. He is known for his contributions to the fields of cosmology and quantum gravity, especially in the context of black holes. He has also achieved success with works of popular science in which he discusses his own theories and cosmology in general; these include the runaway best seller A Brief History of Time, which stayed on the British Sunday Times best-sellers list for a record-breaking 237 weeks.
Hawking's key scientific works to date have included providing, with Roger Penrose, theorems regarding gravitational singularities in the framework of general relativity, and the theoretical prediction that black holes should emit radiation, which is today known as Hawking radiation (or sometimes as Bekenstein–Hawking radiation).
Hawking has a motor neurone disease that is related to amyotrophic lateral sclerosis, a condition that has progressed over the years and has left him almost completely paralysed.
After Hawking was born, the family moved back to London, where his father headed the division of parasitology at the National Institute for Medical Research. In 1950, Hawking and his family moved to St Albans, Hertfordshire, where he attended St Albans High School for Girls from 1950 to 1953. (At that time, boys could attend the Girls' school until the age of ten.) From the age of eleven, he attended St Albans School, where he was a good, but not exceptional, student. When asked later to name a teacher who had inspired him, Hawking named his mathematics teacher Dikran Tahta. He maintains his connection with the school, giving his name to one of the four houses and to an extracurricular science lecture series. He has visited it to deliver one of the lectures and has also granted a lengthy interview to pupils working on the school magazine, The Albanian.
Hawking was always interested in science. Inspired by his mathematics teacher, he originally wanted to study the subject at university. However, Hawking's father wanted him to apply to University College, Oxford, where his father had attended. As University College did not have a mathematics fellow at that time, it would not accept applications from students who wished to read that discipline. Hawking therefore applied to read natural sciences, in which he gained a scholarship. Once at University College, Hawking specialised in physics. His interests during this time were in thermodynamics, relativity, and quantum mechanics. His physics tutor, Robert Berman, later said in The New York Times Magazine:
Hawking was passing, but his unimpressive study habits resulted in a final examination score on the borderline between first and second class honours, making an "oral examination" necessary. Berman said of the oral examination:
After receiving his B.A. degree at Oxford in 1962, he stayed to study astronomy. He decided to leave when he found that studying sunspots, which was all the observatory was equipped for, did not appeal to him and that he was more interested in theory than in observation. He left Oxford for Trinity Hall, Cambridge, where he engaged in the study of theoretical astronomy and cosmology.
Hawking was elected as one of the youngest Fellows of the Royal Society in 1974, was created a Commander of the Order of the British Empire in 1982, and became a Companion of Honour in 1989. Hawking is a member of the Board of Sponsors of the Bulletin of the Atomic Scientists.
In 1974, he accepted the Sherman Fairchild Distinguished Scholar visiting professorship at the California Institute of Technology (Caltech) to work with his friend, Kip Thorne, who was a faculty member there. He continues to have ties with Caltech, spending a month each year there since 1992.
Hawking's achievements were made despite the increasing paralysis caused by the ALS. By 1974, he was unable to feed himself or get out of bed. His speech became slurred so that he could be understood only by people who knew him well. In 1985, he caught pneumonia and had to have a tracheotomy, which made him unable to speak at all. A Cambridge scientist built a device that enables Hawking to write onto a computer with small movements of his body, and then have a voice synthesiser speak what he has typed.
In the late 1960s, he and his Cambridge friend and colleague, Roger Penrose, applied a new, complex mathematical model they had created from Albert Einstein's theory of general relativity. This led, in 1970, to Hawking proving the first of many singularity theorems; such theorems provide a set of sufficient conditions for the existence of a gravitational singularity in space-time. This work showed that, far from being mathematical curiosities which appear only in special cases, singularities are a fairly generic feature of general relativity.
He supplied a mathematical proof, along with Brandon Carter, Werner Israel and D. Robinson, of John Wheeler's no-hair theorem – namely, that any black hole is fully described by the three properties of mass, angular momentum, and electric charge.
Hawking also suggested upon analysis of gamma ray emissions that after the Big Bang, primordial mini black holes were formed. With Bardeen and Carter, he proposed the four laws of black hole mechanics, drawing an analogy with thermodynamics. In 1974, he calculated that black holes should thermally create and emit subatomic particles, known today as Bekenstein-Hawking radiation, until they exhaust their energy and evaporate.
In collaboration with Jim Hartle, Hawking developed a model in which the universe had no boundary in space-time, replacing the initial singularity of the classical Big Bang models with a region akin to the North Pole: one cannot travel north of the North Pole, as there is no boundary. While originally the no-boundary proposal predicted a closed universe, discussions with Neil Turok led to the realisation that the no-boundary proposal is also consistent with a universe which is not closed.
Along with Thomas Hertog at CERN, in 2006 Hawking proposed a theory of "top-down cosmology," which says that the universe had no unique initial state, and therefore it is inappropriate for physicists to attempt to formulate a theory that predicts the universe's current configuration from one particular initial state. Top-down cosmology posits that in some sense, the present "selects" the past from a superposition of many possible histories. In doing so, the theory suggests a possible resolution of the fine-tuning question: It is inevitable that we find our universe's present physical constants, as the current universe "selects" only those past histories that led to the present conditions. In this way, top-down cosmology provides an anthropic explanation for why we find ourselves in a universe that allows matter and life, without invoking an ensemble of multiple universes.
Hawking's many other scientific investigations have included the study of quantum cosmology, cosmic inflation, helium production in anisotropic Big Bang universes, large N cosmology, the density matrix of the universe, topology and structure of the universe, baby universes, Yang-Mills instantons and the S matrix, anti de Sitter space, quantum entanglement and entropy, the nature of space and time, including the arrow of time, spacetime foam, string theory, supergravity, Euclidean quantum gravity, the gravitational Hamiltonian, Brans-Dicke and Hoyle-Narlikar theories of gravitation, gravitational radiation, and wormholes.
At a George Washington University lecture in honour of NASA's fiftieth anniversary, Hawking theorised on the existence of extraterrestrial life, believing that "primitive life is very common and intelligent life is fairly rare."
Hawking was in the news in July 2004 for presenting a new theory about black holes which goes against his own long-held belief about their behaviour, thus losing a bet he made with Kip Thorne and John Preskill of Caltech. Classically, it can be shown that information crossing the event horizon of a black hole is lost to our universe, and that thus all black holes are identical beyond their mass, electrical charge and angular velocity (the "no hair theorem"). The problem with this theorem is that it implies the black hole will emit the same radiation regardless of what goes into it, and as a consequence that if a pure quantum state is thrown into a black hole, an "ordinary" mixed state will be returned. This runs counter to the rules of quantum mechanics and is known as the black hole information paradox.
At the celebration of his sixty-fifth birthday on 8 January 2007, Hawking announced his plan to take a zero-gravity flight in 2007 to prepare for a sub-orbital spaceflight in 2009 on Virgin Galactic's space service. Billionaire Richard Branson pledged to pay all expenses for the latter, costing an estimated £100,000. Stephen Hawking's zero-gravity flight in a "Vomit Comet" of Zero Gravity Corporation, during which he experienced weightlessness eight times, took place on 26 April 2007. He became the first quadriplegic to float in zero-gravity. This was the first time in forty years that he moved freely, without his wheelchair. The fee is normally US$3,750 for 10–15 plunges, but Hawking was not required to pay the fee. A bit of a futurist, Hawking was quoted before the flight saying: }} In an interview with The Daily Telegraph, he suggested that space was the Earth's long term hope. He continued this theme at a 2008 Charlie Rose interview.
Stephen Hawking is severely disabled by a motor neurone disease known as Amyotrophic lateral sclerosis (ALS), sometimes known as Lou Gehrig's disease. Hawking's illness is markedly different from typical ALS because if confirmed, Hawking's case would make for the most protracted case ever documented. A survival for more than ten years after diagnosis is uncommon for ALS; the longest documented durations, other than Hawking's, are 32 and 39 years and these cases were termed benign because of the lack of the typical progressive course.
When he was young, he enjoyed riding horses. At Oxford, he coxed a rowing team, which, he stated, helped relieve his immense boredom at the university. Symptoms of the disorder first appeared while he was enrolled at University of Cambridge; he lost his balance and fell down a flight of stairs, hitting his head. Worried that he would lose his genius, he took the Mensa test to verify that his intellectual abilities were intact. The diagnosis of motor neurone disease came when Hawking was 21, shortly before his first marriage, and doctors said he would not survive more than two or three years. Hawking gradually lost the use of his arms, legs, and voice, and as of 2009 has been almost completely paralysed.
During a visit to the research centre CERN in Geneva in 1985, Hawking contracted pneumonia, which in his condition was life-threatening as it further restricted his already limited respiratory capacity. He had an emergency tracheotomy, and as a result lost what remained of his ability to speak. He has since used an electronic voice synthesiser to communicate.
The DECtalk DTC01 voice synthesiser he uses, which has an American English accent, is no longer being produced. Asked why he has still kept it after so many years, Hawking mentioned that he has not heard a voice he likes better and that he identifies with it. Hawking is said to be looking for a replacement since, aside from being obsolete, the synthesiser is both large and fragile by current standards. As of mid 2009, he was said to be using NeoSpeech's VoiceText speech synthesiser.
In Hawking's many media appearances, he appears to speak fluently through his synthesiser, but in reality, it is a tedious drawn-out process. Hawking's setup uses a predictive text entry system, which requires only the first few characters in order to auto-complete the word, but as he is only able to use his cheek for data entry, constructing complete sentences takes time. His speeches are prepared in advance, but having a live conversation with him provides insight as to the complexity and work involved. During a TED Conference talk, it took him seven minutes to answer a question.
He describes himself as lucky, despite his disease. Its slow progression has allowed him time to make influential discoveries and has not hindered him from having, in his own words, "a very attractive family." When his wife, Jane, was asked why she decided to marry a man with a three-year life expectancy, she responded, "Those were the days of atomic gloom and doom, so we all had a rather short life expectancy." On 20 April 2009, Cambridge University released a statement saying that Hawking was "very ill" with a chest infection, and was admitted to Addenbrooke's Hospital. The following day, it was reported that his new condition was "comfortable" and he would make a full recovery from the infection.
Hawking supports the children's charity SOS Children's Villages UK.
In 1999, Jane Hawking published a memoir, Music to Move the Stars, detailing the marriage and his breakdown; in 2010 she published a revised version, Travelling to Infinity, My Life with Stephen. Hawking's daughter, Lucy, is a novelist. Their oldest son, Robert, emigrated to the United States, married, and has a son. After a period of estrangement, Hawking and his first family were reconciled in 2007.
His view on how to live life is to "seek the greatest value of our action".
Hawking was asked about his IQ in a 2004 newspaper interview, and replied, "I have no idea. People who boast about their I.Q. are losers." Yet when asked "Are you saying you are not a genius?", Hawking replied "I hope I'm near the upper end of the range."
Hawking strongly opposed the US-led Iraq War, calling it "a war crime" and "based on lies". In 2004, he personally attended a demonstration against the war in Trafalgar Square, and participated in a public reading of the names of Iraqi war victims.
His ex-wife, Jane, said during their divorce proceedings that he was an atheist. Hawking has stated that he is "not religious in the normal sense" and he believes that "the universe is governed by the laws of science. The laws may have been decreed by God, but God does not intervene to break the laws." In an interview published in The Guardian newspaper, Hawking regarded the concept of Heaven as a myth, stating that there is "no heaven or afterlife" and that such a notion was a "fairy story for people afraid of the dark."
Hawking contrasted religion and science in 2010, saying: "There is a fundamental difference between religion, which is based on authority, [and] science, which is based on observation and reason. Science will win because it works."

David Howell Evans (born 8 August 1961), more widely known by his stage name The Edge (or just Edge), is a musician best known as the guitarist, keyboardist, and backing vocalist of the Irish rock band U2. A member of the group since its inception, he has recorded 12 studio albums with the band and has released one solo record. As a guitarist, The Edge has crafted a minimalistic and textural style of playing. His use of a rhythmic delay effect yields a distinctive ambient, chiming sound that has become a signature of U2's music.
The Edge was born in England to a Welsh family, but was raised in Ireland after moving there as an infant. In 1976, at Mount Temple Comprehensive School, he formed U2 with his fellow students and his older brother Dik. Inspired by the ethos of punk rock and its basic arrangements, the group began to write its own material. They eventually became one of the most popular acts in popular music, with successful albums such as 1987's The Joshua Tree and 1991's Achtung Baby. Over the years, The Edge has experimented with various guitar effects and introduced influences from several genres of music into his own style, including American roots music, industrial music, and alternative rock. With U2, The Edge has also played keyboards, co-produced their 1993 record Zooropa, and occasionally contributed lyrics. The Edge met his second and current wife, Morleigh Steinberg, through her collaborations with the band.
As a member of U2 and as an individual, The Edge has campaigned for human rights and philanthropic causes. He co-founded Music Rising, a charity to support musicians affected by Hurricane Katrina. He has collaborated with U2 bandmate Bono on several projects, including songs for Roy Orbison and Tina Turner, and the soundtracks to the musical Spider-Man: Turn Off the Dark and the Royal Shakespeare Company London's stage adaptation of A Clockwork Orange. In 2003, Rolling Stone magazine placed him at number 24 on its list of "The 100 Greatest Guitarists of All Time".
In 1981, leading up to the October tour, Evans came very close to leaving U2 for religious reasons, but he decided to stay. During this period, he became involved with a group called Shalom Tigers, in which bandmates Bono and Larry Mullen Jr. were also involved. Shortly after deciding to remain with the band, he wrote a piece of music that later became "Sunday Bloody Sunday". The Edge married his high school girlfriend Aislinn O'Sullivan on 12 July 1983. The couple had three daughters together: Hollie in 1984, Arran in 1985 and Blue Angel in 1989. The couple separated in 1990, but were unable to get officially divorced because of Irish laws regarding marriage annulment; divorce was legalised in 1995 and the couple were legally divorced in 1996. During U2's Zoo TV Tour, The Edge began to date Morleigh Steinberg, a professional dancer and choreographer employed by the band as a belly dancer for the tour's live performances. The couple began dating in 1993, and had their daughter, Sian, in 1997, and a son, Levi, (25 October 1999). They were married on 22 June 2002.
He appeared in the 2009 music documentary film It Might Get Loud.
The Edge has been criticized for his efforts to build five luxury mansions on a 156 acre plot of land in Malibu, California. The California Coastal Commission voted 8-4 against the plans, with the project described by the commission's executive director, Peter Douglas, as "In 38 years...one of the three worst projects that I've seen in terms of environmental devastation...It's a contradiction in terms – you can't be serious about being an environmentalist and pick this location." The Santa Monica Mountains Conservancy agreed to remain neutral on the issue following a $1 million donation from The Edge and a commitment from The Edge to designate 100 acres of the land as open space for public footpaths.
On 1987's The Joshua Tree, The Edge often contributes just a few simple lead lines given depth and richness by an ever-present delay. For example, the introduction to "Where the Streets Have No Name" is simply a repeated six-note arpeggio, broadened by a modulated delay effect. The Edge has said that he views musical notes as "expensive", in that he prefers to play as few notes as possible. He said in 1982 of his style,
"I like a nice ringing sound on guitar, and most of my chords I find two strings and make them ring the same note, so it's almost like a 12-string sound. So for E I might play a B, E, E and B and make it ring. It works very well with the Gibson Explorer. It's funny because the bass end of the Explorer was so awful that I used to stay away from the low strings, and a lot of the chords I played were very trebly, on the first four, or even three strings. I discovered that through using this one area of the fretboard I was developing a very stylized way of doing something that someone else would play in a normal way."
Many different influences have shaped The Edge's guitar technique. His first guitar was an old acoustic guitar that his mother bought him at a local flea market for only a few pounds; he was nine at the time. He and his brother Dik Evans both experimented with this instrument. He said in 1982 of this early experimentation, "I suppose the first link in the chain was a visit to the local jumble sale where I purchased a guitar for a pound. That was my first instrument. It was an acoustic guitar and me and my elder brother Dik both played it, plonking away, all very rudimentary stuff, open chords and all that." The Edge has stated that many of his guitar parts are based around guitar effects. This is especially true from the Achtung Baby era onwards, although much of the band's 1980s material made heavy use of echos. His influence as a guitarist can be heard by acts such as Radiohead, Muse, Coldplay, The Killers, and other bands of the alternative scene.
The Edge sings the lead vocal on "Van Diemen's Land" and "Numb", the first half of the song "Seconds", dual vocals with Bono in "Discotheque", and the bridge in the song "Miracle Drug". He also sings the occasional lead vocal in live renditions of other songs (such as "Sunday Bloody Sunday" during the PopMart Tour and "Party Girl" during the Rotterdam Zoo TV show when it was Bono's birthday).
Although The Edge is the band's lead guitarist, he occasionally plays bass guitar, including the live performances of the song "40" where The Edge and bassist Adam Clayton switch instruments.
The Edge connected with Brian Eno and Lanois collaborator Michael Brook (the creator of the infinite guitar, which he regularly uses), working with him on the score to the film Captive (1986). From this soundtrack the song "Heroine", the vocal of which was sung by a young Sinéad O'Connor was released as a single.
He also created the theme song for Season 1 and 2 of The Batman. He and fellow U2 member, Bono, wrote the lyrics to the theme of the 1995 James Bond film GoldenEye. The Edge, along with fellow bandmate Bono, recently composed a musical adaptation of Spider-Man. On May 25, 2011, a single titled Rise Above 1: Reeve Carney Featuring Bono and The Edge was released digitally. The music video was released on July 28, 2011.
Compared to many lead guitarists, The Edge is known for using many more guitars during a show. According to his guitar tech Dallas Schoo, a typical lead guitarist uses four or five different guitars in one night, whereas The Edge takes 45 on the road, and uses 17 to 19 in one 2.5-hour concert. He is estimated to have more than 200 guitars in the studio.

This work helped further the big-bang theory of the universe using the Cosmic Background Explorer Satellite (COBE). According to the Nobel Prize committee, "the COBE project can also be regarded as the starting point for cosmology as a precision science." Smoot donated his share of the Nobel Prize money, less travel costs, to a charitable foundation.
Currently he is a professor of physics at the University of California, Berkeley, senior scientist at the Lawrence Berkeley National Laboratory, and since 2010, a professor of physics at the Paris Diderot University, France. In 2003, he was awarded the Einstein Medal.
Although Smoot attended MIT, he was not the same Smoot who was laid end to end to measure the Harvard Bridge between Cambridge and Boston; this was his cousin Oliver R. Smoot, an MIT alumnus who later served as the chairman of the American National Standards Institute.
He then took up an interest in cosmic microwave background radiation (CMB), previously discovered by Arno Allan Penzias and Robert Woodrow Wilson in 1964. There were, at that time, several open questions about this topic, relating directly to fundamental questions about the structure of the universe. Certain models predicted the universe as a whole was rotating, which would have an effect on the CMB: its temperature would depend on the direction of observation. With the help of Alvarez and Richard A. Muller, Smoot developed a differential radiometer which measured the difference in temperature of the CMB between two directions 60 degrees apart. The instrument, which was mounted on a Lockheed U-2 plane, made it possible to determine that the overall rotation of the universe was zero, which was within the limits of accuracy of the instrument. It did, however, detect a variation in the temperature of the CMB of a different sort. That the CMB appears to be at a higher temperature on one side of the sky than on the opposite side, referred to as a dipole pattern, has been explained as a Doppler effect of the Earth's motion relative to the area of CMB emission, which is called the last scattering surface. Such a Doppler effect arises because the Sun, and in fact the Milky Way as a whole, is not stationary, but rather is moving at nearly 600 km/s with respect to the last scattering surface. This is probably due to the gravitational attraction between our galaxy and a concentration of mass like the Great Attractor.
The success of COBE was the outcome of prodigious teamwork involving more than 1,000 researchers, engineers and other participants. John Mather coordinated the entire process and also had primary responsibility for the experiment that revealed the blackbody form of the CMB measured by COBE. George Smoot had main responsibility for measuring the small variations in the temperature of the radiation.
Smoot collaborated with San Francisco Chronicle journalist Keay Davidson to write the general-audience book Wrinkles in Time, that chronicled his team's efforts. In the book The Very First Light, John Mather and John Boslough complement and broaden the COBE story, and suggest that George Smoot violated team policy by leaking news of COBE's discoveries to the press before NASA's formal announcement, a leak that, to Mather, smacked of self-promotion and betrayal. Smoot eventually apologized for not following the agreed publicity plan and Mather said tensions eventually eased. Mather acknowledged that "George had brought COBE worldwide publicity" the project might not normally have received.
On September 18, 2009, Smoot appeared as the final contestant on the last episode of the Fox television show "Are You Smarter Than a 5th Grader?". He reached the final question, "What U.S. state is home to Acadia National Park?", to which he gave the correct answer "Maine", becoming the second person and the first man to win the one million dollar prize.
On December 10, 2009, he appeared in a BBC interview of Nobel laureates, discussing the value science has to offer society.
