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 ,  Georges Lemaître  proposed (by 1927) that before the  expansion of the universe  started all the  matter  in the  universe , it formed a gigantic ball of nuclear liquid at  very low temperature . This low temperature was required to provide a sufficient  cohesion  within the  Lemaître 's primeval atom. In 1966,  David Layzer  proposed a variant on Lemaître's cosmology in which the initial  state  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...
