Several of you all have unknowingly referred to the "String Theory", so I figure I'll explain it a bit.
First of all, do note that this is a
theory, and that while math backs it up, experiments in labs haven't because we don't currently have adequate technology to test it.
Anyway, String Theory is the theory that everything in the universe is made up of strings, even all of the atoms we're made up of. In fact, even the universe is just one big string that's constantly expanding. Essentially, String Theory is a theory that, if correct, could potentially explain
everything. Gravity, creation of the universe, what's beyond the universe's supposed infinite yet expanding boundaries. What's strange about it, is that the math states that there are 11 dimensions. Height, width, depth, and even time. However, no one knows what would be in the other seven dimensions if it's correct. So, based on string theory, time travel may be possible. May.
It's an interesting concept, at least, and something that would be really cool if it were true. But, like I said, it hasn't been verified much in labs, it only has the math to back it up.

3) Let's say I went FASTER than the speed of light. I'd start goind faster than the reflected light from the earth, and start seeing things go backwardsas I caught up to the light waves that were previously in front of me. I do this until I see time go back one hour.
It's an interesting theory that would otherwise be correct if it didn't have one major flaw. It's true that if you went faster than light, and assuming light went in the same direction all of the time, you could in fact see what's previously happened. You would just see it, however, you couldn't actually change what's already happened.
However, the flaw is that everything in the universe is always moving, and light expands outward everywhere. So, the light to see what happened in the past wouldn't match up. You could see small bursts, but you can't see a long "picture" because it wouldn't take long for the earth to move and rotate to mess up what you're seeing. Secondly, you forget that light goes out in all directions, so the farther you get from earth, the less of the "whole picture" you see. You'll start seeing less and less until eventually hardly anything will be able to be made out.
