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 , 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...
