I rewatched “Interstellar” and the time dilation dilemma makes my brain hurt. If a change in gravity alters time then wouldn’t you feel a difference entering/exiting said fake planet?
In: Planetary Science
You feel time *locally*. Time always feels the same speed to you because, well, that’s sort of part of the definition of time.
Now, your time where you are may appear different to me, over here, but to you yours is normal and to me mine is normal.
This holds true at every step of the process, going deeper in or out of a gravity well.
