What I'm talking about is more sci-fiy than anything it's probably not possible in a real life scenario, but I'm just curious what would be the result.
For example if we could somehow make an artificial gravity well that only works on a person and does not effect anything around them (on the fabric of spacetime it would basically look like a hole where the person is, while the surroundings outside that person are flat and not affected by the hole).
I'm curious of the possibilities of what could happen, with a higher gravity inside the hole, would the person inside be basically in slo mo compared to everything outside? How would it look from their perspective? Would more light enter their eyes from time dilation? Would they see everything in faster speed? With lowered gravity inside the "hole" (would be a ledge now), the speed of the surroundings should would reverse and they would be the fast ones.
If we increase the gravity would the person look red from the redshift? Also if we increased to the point of a singularity would it just look like a black spot in the shape of a human? Could a person survive in that hole since they aren't accelerating towards anything or does the math break so much we can't really figure that out.
Maybe my theories are just plain wrong, but I think its an interesting concept even though it's not really doable in practice, but the effects of it would be real. Overall it's more or less just a thought exercise. Would like to hear your thoughts.
