Cosmogony

Cosmogony (or cosmogeny) is any model concerning the coming-into-existence (i.e. origin) of either the cosmos (i.e. universe), or the so-called reality of sentient beings. Developing a complete theoretical model has implications in both the philosophy of science and epistemology.

Etymology

The word comes from the Koine Greek κοσμογονία (from κόσμος "cosmos, the world") and the root of γί(γ)νομαι / γέγονα ("come into a new state of being"). In astronomy, cosmogony refers to the study of the origin of particular astrophysical objects or systems, and is most commonly used in reference to the origin of the universe, the solar system, or the earth-moon system.

Overview

The Big Bang theory is the prevailing cosmological model of the early development of the universe. The most commonly held view is that the universe was once a gravitational singularity, which expanded extremely rapidly from its hot and dense state. However, while this expansion is well-modeled by the Big Bang theory, the origins of the singularity remain as one of the unsolved problems in physics.

Outline of space science

The following outline is provided as an overview of and topical guide to space science:

Space science – study of everything in outer space. This has sometimes been called astronomy, but recently astronomy has come to be regarded as a division of broader space science, which has grown to include other related fields, such as studying issues related to space travel and space exploration (including space medicine), space archaeology and science performed in outer space (see space research).

Branches of space science

Astrophysics and Space Science

Astrophysics and Space Science is a bimonthly peer-reviewed scientific journal covering astronomy, astrophysics, and space science and astrophysical aspects of astrobiology. It was established in 1968 and is published by Springer Science+Business Media . The editor-in-chief is Michael A. Dopita (Australian National University).
