Only all radiation will be absorbed by the black hole and NOT radiated back (thus NO Hawking radiation) which feeds the black hole and let the black hole grow from a certain nuclear size!!
I would call it the "CRITICAL Black Hole SIZE" as predicted by the Quantum FFF theory, which says:
The (multi) universe is bouncing or pulsating
It is contracting:
1: by the absorption of the dense Higgs vacuum by all black holes,
(also the origin of the Hubble redshift)
2: by the continuous formation of Super Nova black holes.
It is expanding :
1: by the evaporation of primordial Big Bang black hole splinters into a dense higgs vacuum, only AT THE OUTSIDE OF THE RASPBERRY shaped MULTIVERSE, as long as there are splinters left over from the big bang.
2: by the evaporation of small black holes which are under the "CRITICAL B-H SIZE'"
1: The universe seems to expand by the BH vacuum absorption based Hubble redshift.
2: I also seems to accelerate its expansion because the photons coming from far away have to pass more vacuum absorbing black holes areas.
3: The micro-B-H 's based plasma created inside the Vajra system will evaporate and as a consequence have to be continuously powered by new overunity electricity created by the system itself.
Recently there is a discussion going on about what BH really are:
