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.

As the spaceship speed up, time passed much more quickly than time on Earth. To the people on the spaceship, only a few weeks had passed round-trip, whereas on the earth, something like 80 years had passed. Obviously, in Star Trek the difference in time would not be nearly as substantial.

That is "simple" special relativity, nothing to do with general relativity.
See the twins "though" experiment. This happens everyday. Since particles travelling around the galaxies have a slow wall clock, they disintegrate in what appears for us to be many thousand years, thus allowing them to travel around the galaxies. But when they enter our atmosphere they slow down, their time accelerate back to our "normal" time, and disintegrate in our atmosphere...
