Sorry, I overlooked a mistake you made. The are no unusual physics involved with the "event horizon" of a black hole. It is simply a mathematical region where matter inside that radius must travel faster than the speed of light if it were to escape to the other side of the "dividing line". The center of a black hole (a singularity in some theories) and the singularity of the Big Bang (again, in certain theories) is where the laws of physics (as we presently understand them) break down. IOW, you get mathematical infinities as solutions to equations.

BTW, there is a current theory, not particularly well-known by most people, that postulates that a black hole does not contain a singularity, and that some rather exotic stuff lies within the event horizon.
