Hey! Could a spaceship [assume its a futuristic one with more advanced technology, etc.] orbit a black hole in order to allow time in the universe to pass quicker than for time in the spaceship? How much faster would time be 'outside' than near the black hole-- and how close would you have to be? Could you tread the event horizon, or would significant time dilation only occur inside the black hole itself- rendering the whole question useless? I'm writing a book and need a method of allowing thousands, tens of thousands of years, etc. to pass quickly for only a few generations of humans. Thanks!
