Black hole

A black hole is a geometrically defined region of spacetime exhibiting such strong gravitational effects that nothing—including particles and electromagnetic radiation such as light—can escape from inside it. The theory of general relativity predicts that a sufficiently compact mass can deform spacetime to form a black hole. The boundary of the region from which no escape is possible is called the event horizon. Although crossing the event horizon has enormous effect on the fate of the object crossing it, it appears to have no locally detectable features. In many ways a black hole acts like an ideal black body, as it reflects no light. Moreover, quantum field theory in curved spacetime predicts that event horizons emit Hawking radiation, with the same spectrum as a black body of a temperature inversely proportional to its mass. This temperature is on the order of billionths of a kelvin for black holes of stellar mass, making it essentially impossible to observe.

Objects whose gravitational fields are too strong for light to escape were first considered in the 18th century by John Michell and Pierre-Simon Laplace. The first modern solution of general relativity that would characterize a black hole was found by Karl Schwarzschild in 1916, although its interpretation as a region of space from which nothing can escape was first published by David Finkelstein in 1958. Black holes were long considered a mathematical curiosity; it was during the 1960s that theoretical work showed they were a generic prediction of general relativity. The discovery of neutron stars sparked interest in gravitationally collapsed compact objects as a possible astrophysical reality.

Black

Black is the darkest color, the result of the absence of or complete absorption of light. It is the opposite of white (the combined spectrum of color or light). It is an achromatic color, literally a color without color or hue. It is one of the four primary colors in the CMYK color model, along with cyan, yellow, and magenta, used in color printing to produce all the other colors.

Black was one of the first colors used by artists in neolithic cave paintings. In the 14th century, it began to be worn by royalty, the clergy, judges and government officials in much of Europe. It became the color worn by English romantic poets, businessmen and statesmen in the 19th century, and a high fashion color in the 20th century.

In the Roman Empire, it became the color of mourning, and over the centuries it was frequently associated with death, evil, witches and magic. According to surveys in Europe and North America, it is the color most commonly associated with mourning, the end, secrets, magic, force, violence, evil, and elegance.

The Black

The Black is a rock band from Austin, Texas that formed in 2002 when singer/songwriter David Longoria began collaborating with drummer Andy Morales. The two were later joined by renowned guitarist Alan Schaefer (son of famous guitar maker Ed Schaefer) and Nick Moulos of the Austin band The Crackpipes.

History

The group began playing regularly at Emo's and house parties until Schaefer moved to France to teach English in 2004. Longoria joined major label act ...And You Will Know Us by the Trail of Dead during the band's hiatus, his first performance with them on the Late Show with David Letterman in January 2005. Schaefer joined the rest of the band to support Trail of Dead on their European Worlds Apart tour. During the tour Trail of Dead was the band's backing band for a handful of shows.

Their full-length album Tanglewood was recorded in 2004 and released the spring of 2005 on their own record label K Woo.

The band's next release, titled Donna, was released in the summer of 2007.

The Black Hole

The Black Hole is a 1979 American science fiction film directed by Gary Nelson and produced by Walt Disney Productions. The film stars Maximilian Schell, Robert Forster, Joseph Bottoms, Yvette Mimieux, Anthony Perkins, and Ernest Borgnine, while the voices of the main robot characters are provided by Roddy McDowall and Slim Pickens (both unbilled). The music for the film was composed by John Barry.

Plot

Nearing the end of a long mission exploring deep space, the spacecraft USS Palomino is returning to Earth. The crew consists of Captain Dan Holland, First Officer Lieutenant Charlie Pizer, journalist Harry Booth, ESP-sensitive scientist Dr. Kate McCrae, the expedition's civilian leader Dr. Alex Durant and the robot V.I.N.CENT ("Vital Information Necessary CENTralized").

The Palomino crew discover a black hole in space with a spaceship nearby, somehow defying the hole's massive gravitational pull. The ship is identified as the long-lost USS Cygnus, the ship McCrae's father served aboard when it went missing. Deciding to investigate, the Palomino encounters a mysterious null gravity field surrounding the Cygnus. The Palomino becomes damaged when it drifts away from the Cygnus and into the black hole's intense gravity field, but the ship manages to move back to the Cygnus and finds itself able to dock to what initially appears to be an abandoned vessel.
