I had a brief conversation with a professor of mine and he presented, in short an argument against the existence of black holes. I'm sure you've heard it or a variation of it. It goes something like this: An advisor and his student are near a black hole. They are both wearing a watch, the same watch, synchronized to the same time. The advisor doesn't like his student though. He propels his student into the black hole past the event horizon. On the advisor's watch, he sees the student fall into the black hole and die in a finite amount of time. But the student going deeper and deeper into the black hole, the gravity becomes immense, and time slows to such a degree it takes him an infinite time to fall all the way in. Mind you, he has gone all the way past the event horizon. Thoughts?
