  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.
