Really? I never considered that when it came to light speed travel. I guess it all goes to the relativity theory...Why wouldn’t travelers get younger traveling that fast? Or would they? Just curious...
Perceived time slows down more and more the closer and closer you get to the speed of light. If you could go at C time would stop for you (making it impossible for you to hit the brake peddle!)
As far as I know there is no reverse.
But if there were, it would be way kewl!
