Distance and time. No one seems to have a clue how far a light year is ... I mean maybe ur finding someone in ur own galaxy over a big enough timeline but sorry 2000 light years to the nearest galaxy? Not a chance.

Yep, relativity is a bitch. Even if we could do the speed of light, our time here would pass so quickly that by the time we reached some place that had life, ours might have stopped existing.

And yes, I know a light year is not a measure of time, but distance, but it still takes time.
