Einstein's General Relativity says gravity warps spacetime. Consider a hypothetical scenario:
- A person travels into space from Earth.
- He landed on a different planet in some far off galaxy where time runs slower than Earth. 1 hour on that planet is about 7 years on Earth. The person does not know anything about time dilation or relativity, so he's not aware that gravity slowed down the time.
I was wondering how that person's mind will perceive time. Does the brain think that lot of time has passed but in reality only 1 hour passed? Or is it like, the brain also slows down and adapts to time dilation?
