this was a kind of interesting HW problem i was working on. handed in the solution already, but dont know if it was right. ill run it by the forum and see what the members think. what would a person see if they where falling feet first radially into a Swarzschild black hole. The person is looking at their feet the whole time. Are they always able to see their feet? (especially when their feet are inside the event horizon and their head is not). Once they cross the horizon are they still able to see their feet? Assume of course that they are not stretched apart by the tidal forces.
