Hi, I don't know if I am in the right sub forum or if this topic has been discussed but I'll ask anyway. so I don't think travel into the future beyond what hasn't happened yet is possible and believe it or not, it sounds more possible to me to travel into the past since the past already happened although there are people who think time is nothing more then a man-made construct or just motion so people would always be in the present and once the the past moment/event is gone, its gone for good. if it was possible for a person to travel into the past then is it current excepted scientific theory that one could not change the future or present of the past by traveling into the past or trying to change events in the past? it's like one theory I saw on a science program regarding billiard balls, maybe your familiar with it. and if a aclubare warp drive space ship is ever created(see here http://www.youtube.com/watch?v=kdaMI2wnVBg&list=LLDAnCRZw9SMDaz836h9eotQ&feature=c4-overview) then if the spaceship travels sideways going left or right, I forget witch one then couldn't one travel into the past? even before the spaceship was made?
