I understand the scientific fact that gravity drags on spacetime. The thought experiments I've read and the real experiments done with atomic clocks have been enough to convince me. But now that I understand that, a simple question has come to mind. Would time move slower on the surface of Jupiter than on Earth since Jupiter has more mass? Of course, this wouldn't only apply to Jupiter, but to all objects larger than Earth, I just want to know if I've oversimplified the slowing of time deal or not. And on a side note: Does anyone know of a good book or website that can explain how exactly spacetime itself works? I don't just want a book offering evidence of spacetime bending (e.g. time slowing), but a detailed, possibly mathematical, description of what spacetime is if that makes any sense. I guess I just don't feel satisfied with the analogy of space being like a trampoline. Thanks for any help you all can give.
Why Does E=mc2? (And Why Should We Care?): Brian Cox,Jeff Forshaw: 9780306817588: Amazon.com: Books This is a great book on the subject. It is fairly simplified and does not give great detail but its a good overview of the basic premise. Blew my mind the first time I read it.
It really has more to do with objects relative to other objects but yes. Say one person stays on earth and another takes a rocket that gets close to the speed of light. The person that takes the rocket could return to earth 3 years in their perception of time and it will be somewhere like 10,000 years later on earth and the other will be long dead.
It is known as 'gravitational time dilation' maybe that term will help you find some info you are looking for.
