Document Summary
Pairs of virtual particles pop into existence from the vacuum and quickly annihilate each other. Virtual particles are permitted to exist by the laws of quantum mechanics: proven to exist by the casimir experiment. Inflation -> pre big bang there was an infinite energy field. Our universe simply popped into existence as some of this energy spontaneously converted to matter: e = mc2 -> m = e/c2. Our brand-new, still small universe achieved thermal equilibrium. Next a fraction of a second after the big bang, the universe expanded dramatically by a factor of ~ 1030. Same temperature regions became widely-separated: explains the universal cmb = 2. 728k ~ 3k. Other big bangs arise from infinite vacuum to produce other universes. Recall cobe satellite which confirmed: the cmb ~ 3k (2. 728k) Cobe was later asked to seek very small temperature variations in the cmb: found tiny temperature deviations of +/- 0. 0003k.
