There is an astrophysicist named Stephen Hawking who has an interesting theory regarding time travel. He said that time travel to the future may be possible, but that he doesn't think traveling to the past is possible, otherwise we would know about it. Interesting, but I say that if the theory of alternate dimensions is true, then whatever changes may occur by the result of one's sudden appearance from the future could go unnoticed by us. If the time lines merge or whatever, then to us, things will have always been the way they are, we wouldn't be like, "hey, man, weren't cars not flying yesterday?" Wouldn't make sense.
I suppose I've rambled enough...I'll assume it is possible...
Several things come to mind:
- Visit Nikola Tesla. I would totally help him to get more support on his wireless electricity concept and others, which means that when I returned back to 2010, everything would be far more advanced and I probably wouldn't recognize anything.
- Take a PS2(and tv to plug it into) back to the games of the Atari. I'd take a PS3, but I don't expect to get the thing back, so... better be something cheaper.
- Other mentioned seeing the creation of our planet/Universe... I think that would be a wonderful thing to watch, it would certainly make my list. From the moment of the big bang, up to the creation of our planet... that would be amazing, IMAX wouldn't have **** on that...
- Slap the people who came up with various tv commercials: the Geico gecko and caveman thing, Burger King king, Jack in the Crack's "Jack".. etc. This one would be beneficial to the entire world. :thumbsup:
I wouldn't want to do anything too drastic though... things could change really horribly..
