Just read an article on the Google home page, discussing FTL travel and why it can't happen...
There is one claim in it that I didn't quite grasp... It says you can either move through space or time at Light Speed, but not both. So, if you were travelling at LS in space, that would mean time would stop no?
As such, a 50K year round trip to a star would take no time from our perspective, correct?? (they would feel time, themselves)
