Hi folks,

After some clarification if possible.

Under general relativity, an external observer would see an infalling "victim" essentially freeze at the event horizon of a black hole. My first question is does the victim then see time for our external observer move infinitly fast, or does the infalling victim see the external observer freeze also?

My second question is under the principle of equivelance, does the answer to Q1 apply to motion under special relativity?

Lastly, I've read that under general relativity, the time and radial (or distance?) vectors "swap" once inside the event horizon, in other words, the faster one tries to escape the black hole the faster you actually reach the singularity. Could someone please explain this in a little more detail.

I understand that in many cases one needs to understand the math to appreciate these things, but I haven't done calculus in 20 years, so the more conceptual the answer the better (if possible).

Thanks in advance.

Andrew.
