Coherent degenerated dark matter carrying the spinning hollow spheres ofblack holes violate Einstein’s four dimensional geometry. As a consequence of the weak gravity condition.
The size of a solar black hole has the size of Earth. It has an internal photon horizon of minimized energy. A much smaller size seems to be impossible, always generating a super nova. It is the same for the contraction to neutron star state.
Super massive black holes greater than the minimum of million solar massor bigger have horizons of four times the event horizon.
All Super massive black holes are created in sequence during the inflationary period of the early universe.
