Anyone see the video on the 10th dimension?
I'm sure it's flawed, inaccurate, and simplified to a flaw....but for people like me who suck at physics it's like a drug trip without the euphoric awesomeness
Anyway, time travel is awesome. Back to the Future, Terminator, 12 Monkeys...
There is always that paradox, "if time travel was possible wouldn't someone from the future have come back by now." But, how can they come back if time travel hasn't been invented yet?
I dunno, in my basic physics 101 class my prof said time behaves like a vector that moves in one direction. Wouldn't surprise me if theories of time travel can somehow be supported using complex math.
