Sorry for what may be very basic and unscientific questions, I'm a brand new poster! Regarding black holes: It is my understanding (please correct me if I am wrong) that if an astronaut were to approach and enter the event horizon of the black hole, those watching from the outside would see the astronaut as taking infinite time to enter the black hole, while the astronaut himself would fall rapidly through and be torn apart by tidal forces. My questions are as follows: 1) What accounts for the fact that those watching outside never see the astronaut entering? My guess (rather, understanding, from what little I've read) is that the light from within the event horizon cannot escape to convey the descent of the astronaut; instead, only the light that barely escape from the black hole's clutches is transmitted, constantly showing the astronaut's entrance. 2) If those watching see the astronaut's entrance as taking an infinitely long time, could they leave and come back fifty years later and still see an image of an astronaut at the edge of the black hole? Could someone wandering along in a space ship see the projection of the astronaut still at the event horizon?
