The paper argues that supermassive spinning black holes at Galaxy centers are spinning whirlpools which translate impulse energy acting towards blackhole centers as cosmological expansion energy and gravitational energy,one almost balancing the other. The blackhole interiors are quantum entangled with spin coupled states high in mutual information,leading possibly to negative information,that can express as dark matter. The cosmological fluids in blackhole interiors have quantum vortex flows and turbulence,so that the ergodic boundaries can cause negative temperature states,with dark energy like effects in blackhole interiors,prior to onset of turbulent vortex flows and ultrafast thermalization of event horizons,with coalescence of white hole like entities,associated with worm holes or ER bridges as Susskind equivalents of quantum entangled states.
