Hm well, I'm not too sure what you're asking - punctuation would help.
But here's what Einstein's theory of relativity (best model at the moment, been verified extensivley):
People can't move at the speed of light - it's the universal speed limit, only things that have no mass like photons can move that fast. But let's
say that you're moving so close to the speed of light that it doesn't make a difference. Theoretically, your mass would be infinity (mass as in
resistance to force, not actual matter). According to the postulates of relativity, you would expereince time exactly like normal - however, time
you observe happening on earth to you would always be the same. Eventually, you would return to earth, and you'd feel as though you'd
aged 200 years, although the people on earth would have aged much, much longer. (assuming you're accelerating at a pretty speedy clip).
I know this is confusing, but always remember, that there is not one set "time" for every part of the universe -time is defined only locally. WHich
is why I tend to smirk at the time travel crowd, because really, every time you accelerate you're effectivley commiting time travel.
