History of the Big Bang theory scales, has no preferred directions or preferred places. Hubble's idea allowed for two opposing hypotheses to be suggested. One was Lemaître's Big Bang, advocated and developed by George Gamow. The other model was Fred Hoyle's Steady State theory, in which new matter would be created as the galaxies moved away from each other. In this model, the universe is roughly the same at any point in time. It was actually Hoyle who coined the name of Lemaître's theory, referring to it as "this 'big bang' idea" during a radio broadcast on 28 March 1949, on the BBC Third Programme. It
Cold Big Bang of the universe was near absolute zero. Layzer argued that, rather than in an initial high entropy state, the primordial universe was in a very low entropy state near absolute zero. The mainstream version of the Cold Big Bang model predicted an absence of acoustic peaks in the cosmic microwave background radiation and was eventually explicitly ruled out by WMAP observations. Cold Big Bang Cold Big Bang is a designation used in cosmology to denote an absolute zero temperature at the beginning of the Universe, instead of a (hot) Big Bang. In an attempt to understand the origin of atoms,
