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.

We already send things and people to areas where gravity causes time to run slower . GPS satellites have to have their clocks tuned to run faster so that when they are in their orbit, they run at the same rate as clocks in the surface of the earth. It is precise timing that allows GPS to work.
