Time travel

[2fish]

There have been many shows, games, books, and every other source of entertainment that have discussed time travel. Those I can think of off the top of my head are stargate, back to the future, and blackadder.

Now I want to know what you think is the coolest example of time travel is that you have ever seen, read or witnessed. Also for those members that like to stick to the laws of our universe: what is the most realistic version of time travel that has been used by the media?

My favorite is when the people go back in time take action but only see the changes once they come back to the present time see blackadder.

I fear that should it be possible reality would be much harsher than that. I think that if you went back in time and distracted the guy who protected your great^12 grandparents from a murderer then you might just go poof as you would never had been born.

Thoughts? Ideas? Experience?

My personal favorite means of time travel in all of fictional history.

There was this short novel I read a while back about time travel, where time fixed up itself - you want to shoot your grandfather, poof you're back in your time. You're go to the past, make a crossbow that is later used against you, poof the crossbow dissappears from existance. It was a rather refreshing and interesting look on time travel without pesky paradoxes (honsetly most shows treat those as world shattering when infact they aren't in some theories).

Yes, timesplitters proves how awesome time travel would be. It also opened up a debate i'd never thought i'd have, snowmen vs ginger bread men.

Unfortunately, if you sent a single atom back in time, it would alter the flow of atoms and therefore would prevent itself from going back.

Forget humans going back, i doubt you can even send a single photon back. Reverse time travel is most likely impossible.

And for those of you who will say, "everything that will happen, has happened". Quantum mechanics makes that impossible. The future position of every particle is not set. Over time, the probabilities blur any kind of future prediction. You might be able to know what "most likely will happen" for, at most, a few minutes into the future.

Sad really, i always wanted to go chill with the ancient Greeks.

Not if you consider an infinite multiverse, where each possiblity for every position of every particle is played out in each individual universe. Basically the whole idea behind time lines - you don't so much go into the past as go into a copy of your past (or future for that matter) so upon arrival back to the present you either return to the present of your timeline (making the travel futile since you didn't change anything) or the present of the "altered" timeline - the universe where the natural order of things is exactly how it would be if your time travel changed history (making paradoxes obsolete - for instance killing your grandfather would result in your copy not existing in the alternate present but you "original" still would).

But then thats not time travel is it???

Its sliding...

Well, yes precisely. But its just a technicality. You will still be able to travel to a place that is indistinguishable from your past/future and return to an "altered" present. So all the perks of time travel and none of the problems (like it even existing and paradoxes).

Time traveling in Breakdown was pretty fun. You were the only superhuman around that could still resist the enemy.
