I saw a documentary on TV once about how some scientists think that if you could travel at the speed of light around the milky way and come back to earth, it would take something like 32 years. However, on earth they think that either 100 or 1000 (cant remember which) years would have passed on earth, effectively making time travel possible.
I myself don't agree or disagree with this but I wont to present it as a class discussion at college. If anyone knows this documentary and where i can find it online please help me!
Thanks.

I don't know the specific documentary you saw, because what you said is very common in physics videos. Look up "twin paradox" on youtube, this is what your talking about. When you travel close to the speed of light (you can't travel at the speed of light), your time will be dilated, so you won't travel as far in time as someone at rest. This is not questioned, this is tested fact (Einstein's Special Relativity)

Well, the closer to the speed of light you go, the more time dilation you experiance. I don't know the equation, but it's perfectly possible to travel for 32 years from your perspective, and have several hundred years pass on Earth.

Multicellular organisms CANNOT survive lightspeed travel. Simple.
People who think about this stuff are Wasting their time.

No it doesn't take take 32yrs but I remember couple sec or min I'm not sure...
