Reading this question and response (id: 1102456893.Ph) reminded me of something I have been curious about, involving hypothetical near or at lightspeed travel. In the above referenced question, it deals with how light would percieve time, if at all, since as something approaches light, time dilation occurs, and according to relativity, at lightspeed time would esentially stop. So, with that in mind, pretend we send out a ship at, or near lightspeed to the nearest star, which if I am not mistaken in roughly 4 lightyears away. As observed from earth the round trip would take around eight years give or take, correct? But for the person doing the traveling, would the trip seem exceptionally short? or if at lightspeed, instantaneous?
