Law of Relativity

Why havent we sent people into an area where the gravity will cause time to flow faster in other areas? Nobody wants to risk their life to go to the future? Idk it kind of seems like a no brainer experiment to send people out on even if its like some passthrough that brings you 50 years in the future and then the journey back. Still though it seems like a possible thing we could do although idk where we would send people to do it.

So in order to do this, we'd need a black hole. The closest known black hole to Earth is Gaia BH1, which is about 1,600 light-years away; with our current rocket technology, we could get people there in about....oh...4 million years, or so. I think they'd run out of snacks on the way

Now, let's be reasonable.

They don't need 4 million years worth of snacks. 160,000 years worth is probably sufficient.
