Ya mean, the real humans are massively advanced and we're trying to relive our glory days? And since we're sitting around a black hole, does that mean time here on Earth is moving super-fast, relative to our blackhole brethren?
The movie Interstellar kinda goes down this route...
The time dilating effects only matter for observes in different regions of space time. So if you're a billion miles from the black hole, watching someone fall in as they flash a light at you.. the flashes get farther and farther apart - from your
perspective. They eventually take hours, days, and months, and then years to reach you. The last flash before they fall in never reaches you.
From their
perspective, they're still flashing at once per second.
If we're all simulated intelligences in a civilization orbiting a black hole, then our absolute (i.e. time in the real universe, not our simulated time) would proceed at whatever rate is going on for our advanced descendants.
When you're talking about such advanced computation, it's difficult to say how much real time would be elapsing for our simulated time. In principle, it could only be seconds in the real universe - from the start of our simulation 13 billion years ago to now. Or it could be millions of real years to simulate one second of ours - who knows.
Indeed it's not really that important, since the limiting factor is going to be the amount of energy needed to run the simulations. In such a future, energy is dwindling and will eventually run out. Time will extend infinitely far into the future, so even if a second of our simulation takes a million "real" years, it doesn't matter.
Such a simulation would be the next best case to finding a way out of our universe into a younger one. If you can't actually get away, you can at least simulate a time when life was better.
