'''Cosmology''' is the study of the structure and evolution of the [[universe]].
Ancient and [[medieval]] cosmologists were common, usually oriented around a world view of a stationary, flat earth as the center of the universe. [[Aristarchus]] understood that the [[earth]] was spherical and circled the [[sun]]. With the increasing sophistication of observing techniques and equipment, a more modern understanding of the universe emerged.
Modern cosmological theories take into account [[Einstein]]'s [[Theory of Relativity]] and the recession of [[galaxies]] shown by [[red shift]]. Today the [[Big Bang Theory]] is the theory that receives the most notice in scientific circles, but the [[Steady State Theory]] is still advocated as well. [[Theological]] issues often play a role in questions of the past of the universe and how it came into being. Whether [[God]] is in the equation of not severly changes the possibilities.
