Sure. It'd be weird, but sure.
It'd also be completely undetectable for us... but sure. Even for a non-spinning, non-charged black hole that have these exotic dynamics, if the black hole is large enough then humans wouldn't be ripped to shreds by tidal forces for a while. I can't remember the exact numbers, but I vaguely recall that for a black hole roughly the size of our solar system, for example, we wouldn't get ripped apart for a couple years after falling in. In rapidly-spinning black holes, there are exotic regions where you can delay that fate -- indefinitely, perhaps. |

Maybe but wouldn't you starve to death?
If there is a single truth about Magic, it is that nothing on earth so efficiently evades it.

I like how the professor qualifies it as any life there would have to be incredibly advanced.
Advanced enough to be able to defy the known laws of physics- you'd have to have tremendous power to remain in a stable orbit inside the event horizon of a black hole.

How strange to say "know to be uninhabitable" - when from the perspective of something falling through the event horizon it's just freefall. As to escape velocity and the "tidal forces" for something in orbit inside the event horizon... anyone recall how to calculate Roche's Limit?

Maybe we already are in a black hole.

For example, supermassive black holes have something on the order of 10^28 solar masses. That's something like a Schwarzchild radius of 10^15 light years. It would take an unfathomably long time -- even on the time scale measured by a civilization -- to suffer any of the adverse gravitational effects (like being ripped apart by tidal forces). And that's measuring from AFTER one falls in to the black hole. And for a spinning black hole, there are ways to further delay that inevitability. |

Fair enough. The point I was trying to make was that one doesn't even need a stable orbit inside a black hole to live an exceedingly long (and comfortable) time. At least to the extent that "comfort" is measured by the lack of gravitational weirdness. But an additional point is that, for black holes inside which stable orbits are possible, it's not clear at all what the energy requirements for those orbits are. Indeed, if there are stable photon orbits, then in at least some cases the energy requirements are equal to zero. |

Depends on what kind of "black hole" it is.
