Big Bang and Big Crunch originated by the splitting pairing and recycling via merging of cnetral galaxy S-nova black holes . According to Quantum FFF Theory.
If collapsing stars ( supernova black holes) are the only origin of the contracting universe, then we have no information loss and there is entropy decrease!
Fermions with spin and Lorentz polarization can not enter the black hole according to Quantum FFF Theory, only other black hole singularities can. see also:
