McG, that's as accepted a theory now as it was 25 years ago. If, say, you were on a ship that travelled 10 light years and you were going at 99.99% light speed, you'd arrive there thinking a few days at most had gone by, but people back on Earth experienced 10 whole years. Its a kind of travel into the future, if you want to call it that, since you're seeing a future you'd have to wait a lot longer to see if you didn't make the trip.
