How can anything actually "fall into a black hole" ?
Since time dilation is infinite at the event horizon of a black hole, how can a black hole ever actually gain mass. If you are watching the object enter the black hole, it becomes infinitely red shifted and appear to stop, but never actually disappear. If you are the object "falling into the black hole", time dilation caused by the mass of the black hole causes your time to slow relative to external (nonlocal) space and time nonlocally will accelerate. At the event horizon time dilation is infinite so the universe will pass out of existence. Kip Thorne talked about time dilation in both of these instances in his book Black Holes and Time Warps (pp 190 - 2400, but never answered this question. And no one has ever addressed the time dilation issue as between local and nonlocal objects.
