Template:Stub The Big Bang Theory models the Universe as expanding outwards from a very hot, dense state approximately 14 billion years ago. It was first proposed by Georges-Henri Lemaitre and was observationally verified by Edwin Hubble[1]. Later George Gamow predicted that the Big Bang would leave an observable microwave background radiation. This radiation was subsequently discovered by Bell Labs and found to be close to that predicted by Gamow (Gamow predicted a background radiation level equivalent to a roughly 3 K black body object, and the observed level is that of a 2.725 K body).
Observations of distant supernovae indicate that the Universe is actually undergoing accelerated expansion[2][3]. Modern galaxy surveys[1][4] and recent observations of the microwave background[2][5] have corraborated these claims.
Creationist and Theistic Evolutionary Views
Young earth creationist scientists hotly contest the Big Bang Theory stating that it is scientifically unsound [3] [4] [5], though no such criticisms have been published in peer-review scientific journals. Young earth creationist use the Bible, which they believe to be a literal truth, to trace lineages to estimate the age of the Earth to be around 6,000 years. This idea might be true, but does not conflict with Big Bang Theory because the young earth creationist cosmology is non-scientific (in the sense that it does not offer mathematical or logical models which make definite, testable predictions and describe or account for observated phenomena).
In contrast to young earth creationists, Old Earth Creationists and Theistic evolutionists agree that the Big Bang occured.[6]. Some Old Earth Creationists and Theistic Evolutionist argue that the Big Bang is in fact mentioned in the Bible. [7]
