ts of creation. In short, the Big Bang theory is one that incorporates other theories in its attempt to explain the evolution of the universe. Though much evidence supports, the Big Bang theory, there are still questions, which remain unanswered. Other theories that attempt to explain the origin of the universe exist, but the Big Bang theory has become the standard model by which others are measured.
The history of the Big Bang and cosmology was born when Albert Einstein developed his General Theory of Relativity in 1915, and his first cosmological paper in 1917, when Einstein attempted to make the equations of relativity fit together with the incorrect belief that the universe was stable and static, with no beginning nor an end (Monsters 103). Einstein's theory of gravitation of space-like bodies, general relativity, has identified gravity with the curvature of space-time, the four-dimensional manifold that consists of the three space dimensions combined with time (Silk, Big Bang 1980 13). Any event can be described in terms of its path and location in space-time. In particular, the light from distant galaxies logically follows the shortest possible path, called a geodesic. The manner by which one looks back in time is by geodesics; galaxies are almost like time machines, with the light from most distant galaxies traveling through space-time since before the earth was even formed, 4.6 billion years ago. The most distant galaxies are at a distance of ten billion light years, basically providing a look-back in time of ten billion light years as well.
Einstein's theory of relativity received solid confirmation in 1919, when the deflection of light from distant stars by the sun was measured during a total eclipse. The cosmological implications of Einstein's theory of relativity began to receive intensive examination. The idea of the Big bang and an expanding universe which challenged Einstein's idea of a static and unchanging universe,...
