there you go on that.
in human speak
if you get near the speed of light time for you slows down relative to the rest of the universe so you can like 99.9 etc the speed of light and it doesn't seem like months. the problem is the rest of the universe goes by faster. It deals with space "actually shortening" between the distances due to the extreme speed. Speed is the answer.
generation ships and cryo sleep are autism.
