First let me say that I am a premed student who's just interested in physics so please forgive me for asking stupid questions, but I sure do have a lot of questions that I feel could best be answered by human beings rather than by looking them up and just getting more confused. So as I understand it, all the matter that crosses the event horizon gets compressed at the singularity after a finite amount of time, but what does that mean? Does every particle that enters the black hole occupy the same 0-dimensional point at the center? Does this mean that there are a huge number of particles at the center of each black hole that all occupy the exact same three-dimensional point? I read the other day about the concept of a Bose-Einstein condensate the forms when the temperature of a material is dropped to about a microkelvin above absolute zero, where the particles' wave functions begin to interfere because they are so close to each other. If each of these particles at the singularity of a black hole occupy the same 0-dimensional point, does that mean their wavefunctions are all interfering? Does a particle that reaches a singularity have a temperature/internal energy associated with it, or does it reach absolute zero? Do particles at a singularity have mass/rest energy? Also, if the singularity itself has a mass associated with it, and this mass is growing with each new victim that gets sucked into the event horizon, does that mean that the gravitational force the singularity exerts on outside objects increases infinitely over time (according to GMm/r^2)? Also, I heard that the speed of massless gauge bosons are all c (the speed of light), and that this would include the yet-to-be-observed graviton. If a graviton and a photon are both massless particles that both travel at the speed of light, why is it that light gets sucked into a black hole? Don't the photons and gravitons have the same velocity? Also, if a photon is massless, and assuming GMm/r^2 still applies at the quantum level, what property of a photon is the graviton acting upon that would cause the photon (or any electromagnetic wave, really) to be "sucked into a black hole"? If anyone could answer even one of the above questions (not necessarily all of them), I would really appreciate it, because they are bugging the hell out of me and this I suspect this is probably the last chance I'll get before medical school to think about things like this.
