It is suggested to be retarded by the existence of local "empty Axion-Higgs field vacuum bubbles"
How could such a singular retarded big bang black hole splitting take place?
According to Quantum FFF Theory, only if the Axion-Higgs pressure on the Black Hole nucleus is reduced.
So: inside empty Galaxy bubbles forming so called tendril galaxies.
