time travel is impossible based on the principle of conceservation of energy, there is only so much energy and matter in teh universe, so tirod is on the right track he's just not being the most clear in getting the point, but anyways, if you were to travel back in time you would have to displace teh matter that you are sending back in time (which i'd love to see you to figure out how to do that), the other possiblity is that you can ignore the law of conservation of energy for brief periods of time, but that's beyond the physics most of you have taken at this point (or will take), but in short it's impossible if it would ever be possible it would be many lifetimes beyond ours, the only possiblilty is you can manipulate the passage of time by traveling speeds near that of the speed of light

if we could, wouldn't we (our future selves) come back in time and fix mistakes that have been made?
technically, it could be possible according to einstein. but only if you could move faster than the speed of light.

The problem is to start with teletransport. Thats the process of moving object from place to place. They can do it now by breaking down molecules and putting them back together in another place BUT, when it comes to our brain, our brain is soo complex and teletransport doesn't allow the brain to retain memory so basically if we could teletransport, we would have a brain of an infant. As soon as we can teletransport, we can thinkg about time travel.

i don't agree with all the conservation of energy stuff. you are simply shifting the matter to another time. in fact it happens all the time. see when you stared reading this your matter was say 10 seconds ago. the universe didn't end did it? anyway if you are really interested in this stuff, my physics prof. from a couple semesters ago is actually theorizing about this type of stuff. it's all about taychons.
