However, it is impossible to accelerate a mass to the speed of light, so at least some time would pass for you during transit (and obviously time would pass while you were actually accelerating to near-light speed, and decelerating at the other end, for that matter). If you travel far enough at near light speeds, though, it would be like a time machine that could take you to the future.

are you sure about that? no time would pass for you? I thought you still aged. I'm not disagreeing with you, I remember learning this in astronomy 205 which was like 7 years ago.
