I have avoided commenting in this thread for seven years, because, quite frankly, it's the dumbest thread in history. Titor is so clearly fraudulent that it would take a two year old child to believe him. But I noticed there's one scientific issue at the very beginning of this epic thread which categorically invalidates the entire enchilada.
Time travel from 2039, 20390, 203900, or any other future date, to now or the past, is impossible because it's currently impossible now. Epic stated, "I'm not going to say that it's impossible, because I believe that there are some things out there that are beyond our understanding based on our current knowledge of science." But if you were to create a wormhole, slinging it far into space and looping it back around to earth, as required, you could only travel back in time to the original creation of the wormhole, since entropy cannot be reversed. (For the sake of simplicity I'm also neglecting to mention the reasons why a wormhole cannot feasibly be created or safely used.) And so since current understanding and knowledge of science says traveling back in time is impossible, and since no wormholes have ever been created, it's impossible for any future innovations in science to produce a time traveler back to this time.
