Another Thread about Time Travel & Prometheus

Hi all, I know this has been discussed before, but I think it merits more debate and thoughtful speculation, besides until we get a new trailer old theories are going to be re-hashed. So anyways here goes my idea about Prometheus and time travel. Near faser than light travel will be in the movie, therefore, time travel will be in. I have read that RS was going to tackle this issue. But I dont have any fear of it ruining the movie ( Some people have expressed a disdain at seeing this in the movie). I have faith that RS will handle this mind bending theory in todays scientific knowledge. If I am correct, if a person or persons inside a craft travel at near the speed of light then time seems to travel slower for those that are moving at those reveletistc speeds to those outside observing. So in otherwords, time for the occupants in the spacecraft will be normal for them say 1 to 1. Outside, lets say on earth, it would be 10 to 1 to those inside the craft. So 100 years of near light travel (in hypersleep) for the space travelers would be 1000 years in the future for Earth. I believe RS wants us the movie goers to think about what it means for Humanity to become a space fareing being, what are the consiquences/ramifications of this achievement. We will see a being or beings going through this. What it has meant to them and their advancement as a space fareing society. I believe it will also be a thought provoking movie, and scary, fun, maybe disgusting ( we only hope, LOL). Lets discuss how this NLS (Near Light Speed)will play into the time lines of Prometheus and Alien.
