Template:Stub The Big Bang Theory models the Universe as expanding from a very hot, dense state approximately 14 billion years ago. It was first proposed by Georges-Henri Lemaitre and evidence for the expansion was observed 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).
The term "Big Bang" implies an explosion of matter into pre-existing space, but the theory actually indicates that space is dynamic and more space is constantly created in the interstices between particles as the density of the universe falls. The Hubble redshift is a consequence of this stretching of the fabric of space.
Observations of distant supernovae indicate that the Universe is actually undergoing accelerated expansion[2][3]. Modern galaxy surveys[4][5] and recent observations of the microwave background[6][7] have corroborated these claims. Conventional wisdom is that the acceleration is caused by some sort of dark energy.
Creationist and Theistic Evolutionary Views
Young earth creationist scientists hotly contest the Big Bang Theory. They trace lineages in the Bible to estimate the age of the Earth to be around 6,000 years.
In contrast to young earth creationists, Old Earth Creationists and Theistic evolutionists agree that the Big Bang occured.[8]. Some Old Earth Creationists and Theistic Evolutionist argue that the Big Bang is in fact mentioned in the Bible. [9] However, the Bible makes no mention of a "Big Bang", instead speaking in terms of firmament and a celestial ocean (the "waters below" and "waters above"), a feature found in much early thought.
