.The Cold Big Bang by explosion of the Big Crunch String Black Hole followed by Herbig Haro star heating.
How did our universe begin?
The hot Cosmic Background (CMB) seems created by new star breeding ( Herbig Haro) between two equal sized (15%) (new physics) expelled black holes after a cold big bang black hole explosion, observable as Bowshocks outside older Nebula.
Each black hole seems equipped with a Penrose proposed trapped space horizon together with fermion creation and repulsion forming a plasma disc and stars between jets.
In Quantum FFF Theory, it is postulated that the Big Bang was the cold Big Bang of a decaying String nucleus based Dark Matter Black Hole into smaller ones and heated up by equal sized Herbig Haro Black Holes with star forming in between.. ( Quantum FFF Theory) FFF =Function Follows Form, from stringy particles to Herbig Haro system black holes equipped with a Fermion creating (plasma) and repelling horizon.
Both big bang elements are examples of a violation of the second law of thermodynamics, the big bang explosion and also each fermion creating and repelling black hole horizon of each black hole and also dual Herbig Haro black hole systems .
NO singularity it was, but the explosion of a relative large string nucleus filled with primary strings compressed by the decreasing pressure of the primary string vacuum by eating it.
At the moment that the vacuum compression became equal to the internal pressure of the string nucleus, the BB explosion started.
I suggest that this string nucleus can be also called the Big Crunch black hole of a former (multi) universe.
