Cosmology ( from the Greek kósmoV: universe, and also structure, order, and logoV: Word, doctrine ). Part of astronomy; science that the universe as a unit of connections is a whole, and any portion of the universe covered by [90] astronomical observations as part of saying all. Modern Cosmology has become, in fact, a border region in the line of contact between astronomy, physics and philosophy. The first and naïve cosmological representations emerged in remote antiquity as a result of the man's desire to understand his place in the universe. The data accumulated by the observation and security are suggested by the Greco-Roman philosophy do that after the confused apparent motion of the planets should hide the movements real and subject to law, led to create the geocentric system of the world system, was replaced by the heliocentric system after a bitter struggle with the Church and the scholastic.?? When Newton had discovered the law of universal gravitation, it was possible to raise the cosmological problem as a physical point on the behaviour of an infinite of gravitation masses system. It turned out, however, that serious difficulties, the cosmological paradoxes arose to do so. Modern relativistic cosmology, consisting of cosmological theories based on the theory of relativity, eliminates these difficulties. However, others of which do use large-scale idealist fideists to «explain» their conclusions about the "expansion" of the universe and even the 'creation' of the same, have sprung up 38; c. The real significance of modern cosmological models is that they give an idea of the general laws of the structure and development of the Metagalaxia and therefore constitute a step essential to the infinite process of cognition of the universe, infinite in space and in time.
