This paper looks at the Big Bang Theory. It examines the history of the theory and the scientific ideas on which it is based. It also examines some of the evidence proving the Big Bang and addresses some of the more common arguments against it. |

The Search for Creation Man seems, by nature, to be a curious creature. We are always looking for explanations for natural phenomena. We have attributed the sound of thunder and lightning in the sky to Thor.

The Big Bang Theory The currently accepted model of the Big Bang is "that the the universe is not static but is expanding and that the expansion began in an incredibly hot, dense Big Bang approximately 13.72 billion years ago" (Krause, 2012, p. 25). This hot, dense bit of matter was only a few millimeters across and contained all of the matter and energy that makes up our universe and as it expanded, it cooled and over the billions of years of existence the universe settled into its current state. In 1916 Einstein proposed his new General Theory of Relativity that built upon Newton's Universal Theory of Gravitation which showed "that gravity is responsible for the motions of both planets and falling objects near the Earth" (Fix, p 86). Einstein' theory "describes gravity as a curvature in four-dimensional spacetime" (Singh, p. 502). The original intent of the theory was to explain the inaccuracies of Mercury's orbit when using Newton's law and the Sun's bending of light. The Cosmological Principle is the assumption that if you viewed the universe as a whole "it would appear roughly the same everywhere and in every direction. That is, the matter in the universe is homogeneous and isotropic when averaged over very large scales" (Universe 101, n.p.). In 1929 Edwin Hubble, for whom the Hubble Space
