Not according to Q-FFF Theory:
There was only one big exploding string black hole nucleus, compressed by the decreasing vacuum lattice of the former multiverse. The equilibrium between the vacuum and black hole internal pressure was changing, what started the black hole Big Bang.
It was a dark matter black hole (and deep cold) before splitting and making mass and stars by dual string black hole Herbig Haro systems. see next posts.
