Ohhh kayyy, Thanks! I get that part now 1 more quick question that I'd rather not open a whole new thread for. For relativistic mass, could e=mc^2 be used (as a simple explanation obviously) to explain it. For example, as E(kinetic) increases, the relative mass would have to increase to keep...

Exactly. I want to understand it more than using a rubber sheet. Not only that but I want to understand it, not parrot the answers that I've heard.

So I was watching a video on youtube. http://www.youtube.com/watch?v=QM28eErikAo" It says that the faster you travel through space, the slower you travel through time, and that if you went faster than light, you could go back in time. Is this true? Forget about it being impossible to go...

So if speed increases mass as it approaches c, does the added mass increase the curvature of space-time? The reason why this question is making me confused is because the mass is only increased to an outside observer. Could anyone clarify this for me.

So I'm 16 and just starting to get into relativity. When I learned that bodies of mass bend space time, that got me thinking. So I was wondering whether space-time is sort of like rubber. Can it be stretched? Or is it more rigid and pulled from the outside, like a trampoline. I know this might...
