A 160 MeV Bounce Model of The Big Bang
  To propel the farthest galaxies at 0.5c, the big bang required a core energy of 160MeV. Its baryon-photon ratio becomes $\eta=87.6\Omega_Bh^2$ which is comparable to a supernova. Accretion photons emitted during the prior contraction supplied the CMBR planck spectrum. The finding of primordial 2^H levels varying by an order of magnitude is evidence of large scale structure during nuclesynthesis. Rotating black holes from the primordial shell were the density fluctuations for galaxy formation. Sufficient baryonic matter was recaptured during the expansion to increase the universe scale factor and allow supernovae Ia to occur in a closed universe. A low energy bounce model with zeroing of the stress-energy tensor can solve the hot big bang problems.
