I always though it's kinda depressing how even if we could travel close to speed of light, the time it would take to get to the nearest galaxies would still be hundreds if not thousands of years. However I recently learned that it's not quite so because when traveling at that speed you're also traveling in time, so from your perspective it wouldn't take long at all. It's just that you can't really ever come back because everyone else would be dead by then.
