Geek stuff, sci-fi... Today, the new Star Trek film has seen its official premiere here in The Netherlands tonight, and in honour of that, I figured an article on Space.com about the possibility of faster-than-light travel would make a good fit on OSNews. The article is quite technical, so bear with me on this one. I hope I get everything right.

The idea outlined (and i agree it isn't much) would probably avert relativistic effects, since there is no movement within spacetime as the idea is to move a part of spacetime itself.


Any time you beat light-pulse somewhere (through a vacuum), you will have traveled in time. What clever trick you used to beat the light pulse does not change the fact that you have traveled between two events faster than a pulse of light could, which is an entirely sufficient fact to establish that you have potentially traveled in time.
Potentially because not everyone will agree about whether you have traveled in time or not: if it is not possible for a light-pulse to travel between two events - like if they are happening a light year apart, but only a second apart in time - then not all observers will agree on what order the events happen in (or, really, how far apart in time they're happening). Some people would say you arrived a long time before you left, others might say you took your sweet time making the trip.
