That video was pretty interesting, has it been dis-proven?
Time-travel would be really cool, but it would also really fuck everything up wouldn't it? Many people wouldn't want to live in the present, if people went to the past then they could easily completely change the future (butterfly effect), and if we really discovered time-travel, then doesn't that mean the future already has time-travel and would visit us first? Thinking about it makes my brain hurt.
And now for some shameless advertising of my own thread. Everyone click on the one titled "We're Alive: A story of survival."!!!!!!!!!!
