General relativity suggests: the center of each black hole is a gravitational singularity.
Q-FFF Theory However says, the black hole singularity may be a cold dense knot of
rigid strings compacted and growing by the incoming Gravitating pressure (Casimir)
of vacuum string particles (coined Axions)
Axions are oscillating as a 3D tetrahedral lattice between nodes at the Planck distance
which is elongating around the black holes (redshift origin) which are growing by the
Axion input.
All strings should have come out of the splitting and vacuum evaporating big Bang
nucleus, being the content of the former Big Crunch, inside a cyclic supersymmetric
Multiverse with a maximum 8-12 universes. (see: Q-FFF model, Benjamin Libet:
Veto Free Will)
As a consequence of the string black hole big bang, the big bang was a cold string
spitting black hole area, forming hot Fermion pairs produced at all black hole Penrose
"trapped space" colliding Horizons.
The Fermion pair production (e-,e+) around both Herbig Haro black holes outside the
Penrose Trapped Space Horizon is splitting electrons, with the heavier compound
fermions and the magnetic field.
Together forming protostars, between dual Herbig Haro equal sized black hole systems.
The fermions created at both Herbig Haro bow-shock black holes will form stars which
seem mostly drift by the vacuum polarization and magnetic pressure into the central
dust disc around the protostar.. see:
