Compressed Rigid Stringy Big Bang Black Hole Nucleus.
All Black hole nuclei are compressed by the (Casimir) energy of the oscillating Axion-Higgs vacuum Lattice, even the Big Bang Black Hole,
However, only until the decreasing vacuum pressure has come into balance with the central ( Big Crunch) Big Bang BH, the BB Black Hole will expand and explode into chunky smaller BHs which eventual evaporate into the oscillating vacuum lattice. According to Quantum FFF Theory.
All black holes are assumed to be the same as Dark Matter even the smallest interference black holes such as the Higgs particle, which is of course unstable by the attack of the oscillating vacuum lattice.
