The hypothetical Hawking radiation means that a set of baryons can be finally transformed, "evaporate" into a massless radiation - that baryons can be destroyed. It requires that this matter was initially compressed into a black hole.
If baryons can be destroyed in such extreme conditions, the natural question is: what is the minimal density/heat/pressure required for such baryon number violation? (or while hypothetical baryogensis - creating more baryons than anti-baryons).
While collapsing into a black hole, below the growing event horizon, not only light but also matter has to travel toward the center: any finite limit for conditions is finally exceeded - so baryons should be destroyed there, releasing huge amount of energy (complete [itex]mc^2[/itex]) - pushing the core of collapsing star outward - preventing the collapse. And finally these enormous amounts of energy would leave the star, what could result in currently not understood gamma-ray bursts.
So isn't it true that if Hawking radiation is possible, then baryons can be destroyed and so black holes shouldn't form?
We usually consider black holes just through abstract stress-energy tensor, not asking what microscopically happens there - behind these enormous densities ... so in neutron star nuclei join into one huge, in hypothetical quark star nucleons join into one huge ... so what happens there when it collapses further? quarks join into one huge? and what then while going further toward infinite density in the central singularity of black hole, where light cones are directed toward the center?
The mainly considered baryon number violation is the proton decay, which is required by many particle models.
They cannot find it experimentally - in huge room temperature pools of water, but hypothetical baryogenesis and Hawking radiation suggest that maybe we should rather search for it in more extreme conditions?
While charge/spin conservation can be seen that surrounding EM field (in any distance) guards these numbers through Stokes theorem, what mechanism guards baryon number conservation? If just a potential barrier, they should be destroyed in high enough temperature ...
Is matter infinitely compressible? What happens with matter while compression into a black hole?
Is baryon number ultimately conserved? If yes, why the Universe has more baryons than anti-baryons? If not, where to search for it, expect such violation?
If proton decay is possible, maybe we could induce it e.g. by lighting the proper gammas into the proper nuclei? (getting ultimate energy source: complete mass->energy conversion)
Is/should be proton decay considered in neutron star models? Would it allow them to collapse to a black hole? Could it explain the not understood gamma-ray bursts?
