No. The time dilation is relative, so the person in the black hole would theoretically see his proper time progressing normally, and the universe would appear to speed up.

@Etropalker Do the basic of Special Relativity makes sense, i.e., all observer can get different answers for the order of events and measurement of observations? The only thing that everyone agrees on is causality. Right now, if you look at the sky, you'd measure the age of the universe to be 13.8 billion years. A different observer near a black hole in a heavy gravitational field, could look at the same universe for minutes, and get a much older universe. Both can be equally right because spatial and temporal measurements are all relevant. It just depends on the observer.

@Etropalker What happens at the event horizon of a black hole is analogous to when the observable universe expands and parts become causally disconnected or red-shifted to undetectable wavelengths. If someone or something crosses the event horizon, another observer outside will never get the signal. I could be wrong, but maybe you're referring to the information paradox from black hole evaporation. That's part of quantum mechanics and Hawking Radiation.

@Etropalker Special Relativity and Newtonian Mechanics are flat spacetime, Inertial, none accelerating. Since world lines, Minkowski spacetime are introduced first in Special Relativity, I used it. Your question is where General Relativity and Quantum Mechanics come into conflict because it's a gravity question. You're doing it right using intersecting world-line, but the hard part is the thought experiment. Hmmm... Give me a second..

@Etropalker Did that particle horizon example make sense? I used to struggle to make sense of the event horizon because the outside observer could never see anything cross into a black hole. They should just see it remain stil and never crossing the event horizon. It's the same as galaxy that are moving away from earth because space is expanding faster than the speed of light. We are causally disconnected, but it doesn't take an infinite amount if time to vanish. The photons leaving the "ghost galaxies" only travel at light speed so it would never be able to reach us, even if we waited an infinitely long time. When the black hole evaporates, the outside observer would be just as likely to see the evaporation as we would be able to see something outside the observable universe.

Because it's in orbit and hasn't crossed the event horizon.

While sitting down? Down relativity what? The bus was moving, so down was constantly changing.
