I shudder at the thought of singularities. I'm sure they're just a mathematical tool for glossing over a hole in our knowledge and don't actually exist. I think there is some mechanism, as yet undiscovered, that prevents total collapse.
I believe there is a minimum size for blackholes as they evaporate, if the 'singularity' was of zero dimensions this would not be so.
What I would like to know is why does the singularity' just not gobble itself up ?..what with it being so dense and all that !...should it not just implode into nothingness ?..something must be stronger than the gravity field for it to remain substantial then eh ? If gravity is infinitely strong then should it not just pop out of existence ?
Hawking radiation (also known as Bekenstein-Hawking radiation) is a thermal radiation with a black body spectrum predicted to be emitted by black holes due to quantum effects. It is named after the physicist Stephen Hawking who provided the theoretical argument for its existence in 1974, and sometimes also after the physicist Jacob Bekenstein who predicted that black holes should have a finite, non-zero temperature and entropy. Hawking's work followed his visit to Moscow in 1973 where Soviet scientists Yakov Zeldovich and Alexander Starobinsky showed him that according to the quantum mechanical uncertainty principle, rotating black holes should create and emit particles. The Hawking radiation process reduces the mass of the black hole and is therefore also known as black hole evaporation.Because Hawking radiation allows black holes to lose mass, black holes that lose more matter than they gain through other means are expected to dissipate, shrink, and ultimately vanish. Smaller micro black holes (MBHs) are predicted to be larger net emitters of radiation than larger black holes, and to shrink and dissipate faster.
I wonder if we know enough about Hawking Radiation to recognize it if we see it. If it is a product of vacuum fluctuations where a particle-antiparticle pair is created and one gets caught up in the black hole, what distinguishing characteristic would the escaping particle have? Maybe there's a sign on it that says "I just escaped a Black Hole"
I guess maybe if we noticed gamma radiation at around .510 MeV that comes from some black-hole candidate we might assume it to be Hawking radiation. It would come from positron-electron inhalation in proximity to the candidate.
