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.
Time travel is easily possible, just not in the reasonable concepts TV and movies put it into.
As someone stated below, every time you basically move anywhere - you're traveling forward in time.
If you go into space, and remain there for long periods of time, and then come back to Earth, you will have aged at a less rapid rate than people on the planet.
To travel in time is to travel faster than the speed of light, and since everything has a mass, minus light - and in order to go faster you need to produce more energy in relation to how much mass you have, you will need an infinite amount of energy even if you have relatively no mass.
Now, there is a theory that states something like :
Picture a piece of paper, put a dot at one end, and a dot at the other. It would take a long time to draw a line between those two dots as is - but if you fold the paper up, and line the dots up and poke a hole through the paper - you're instantly at the other dot, and didn't have to go through the middle of the paper.
Demetri Martin said it best: "I have a time machine at home. But it only travels forward in time, at normal speed. It's more just like a cardboard box with 'Time Machine' written on it."
