With the exception of Hawking radiation - which (as I understand) is the capture of one member of a virtual pair of photons that appears at the event horizon by the black hole with the "escape" of the other photon into the surroundings - I find no conjectures that any particle of mass could cross a black hole's event horizon and then pass back across the event horizon - essentially "escaping" from the black hole in the sense that it avoids falling into the singularity. I am not claiming others have not addressed this conjecture , just that I have not found any in my literature search.
Certainly there are many published explanations that say "no", but consider the following scenario:
Although it appears that an electrically charged black hole may not ever occur naturally, there are two general-relativity solutions that do allow for the possibility of an electrically charged black hole (the Reissner-Nordstrom and the Kerr-Newman black holes).
If a charged particle's velocity trajectory intersected the event horizon of a charged black hole at the limit of a tangent trajectory (an infinitesimal fraction of a degree below the tangent and therefore crossing the event horizon);could there be a case where the magnitude of the electric charge of the black hole and the opposite magnitude of the charge of the particle of mass combined with a sufficiently high magnitude of velocity of the particle would allow the particle to then recross the event horizon into normal space?
Essentially, could the coulombic repulsive force between the particle and the singularity diminish the net force of the singularity acting on the mass of the particle sufficiently for this hypothesized escape trajectory to be possible?
