Quantum Correction for our Big Bang Bouncing Universe
  Our Universe has multiple examples of unexplained gravitational losses in black holes and neutron stars.Squeezed to a certain size, nucleons are not easily compressible further. Gravitational loss will allow galactic black holes to cause dark energy and the big bang to start as a bounce. A cold shell and a hot core will enable a Planck spectrum and galaxy formation in the early universe. Thus the universe was never radiation dominant. A quantum correction to general relativity much less than planck energies will cause a cyclical universe.This paper resolves the tension in the Hubble constant derived from CMB measurements in the early universe against that measured in cepheid variables in the late universe.
