So lately I've been watching a lot of videos about time travelers like John Titor and the stuff from ApexTV (entertaining but obviously not intended to look real) so it made me curious about wether fellow OSSers believe in this kind of phenomena or not. I personally think some kind of time travel is possible, since time is just another part of our reality. Wether it is like in the movies, I'm not sure. But in one of the videos I was watching, probably John Titor's (who was probably also a hoax) somebody explained that when you travel back in time you technically create an alternate timeline thus, not really altering the past but creating a new reality completely separate, and I thought this was really interesting. Also, as part of this thread, since this is OT, what would you tell your guitarist (or whatever you play) from the past if you could travel back in time? Feel free to quote old threads as well, although I don't know if that counts as necrobumping.
