How to Build a Time Machine
frank249 writes "The September issue of Scientific American has an article discussing the possibility of time travel. They say that it wouldn't be easy, but it might be possible. It could be a while until we can expand worm holes and tow them to a neutron star but didn't someone say that if it is possible it will happen. If it is impossible it will just take a little longer."
It ain't easy, but not impossible. Heck, there are gazillion things that are not easy but not impossible, doesn't mean it'll happen anytime soon.
Time travel. Possible? Yes. It happens relativly speaking every day.
Nonsense. Time dilation is not time travel. For whatever it's worth, nothing can move in time, forward or backward. The entire spacetime of relativity is frozen from the infinite past to the infinite future. I'll let the smart ones (i.e., the ones who were not irreparably brainwashed) figure that one out. In the meantime, those of you who are really interested in the truth can take a look at this following link for a complete debunking of time travel and other crackpottery from the physics community. Wild eyed Star-Trek fanatics need not bother.
