I can't think how time travel could be possible. Wasn't there a movie where people traveled faster than light and what was a few seconds for them was really like twenty years? But then how would they get back?

I think if time travel is possible then it should only be used to go into the future. Going into the past just doesn't sound like a good idea. If you went back in time to stop something from happening then it never would have happened so you wouldn't have gone back in time to stop it from happening. It's very confusing.

We travel in time now. Go here and look for it. Something to do with worm holes.

Yes, I believe time travel is possible. However, you can only travel into the future. There is no way to go back. And actually "time-traveling" wouldn't be exactly what you're doing. It's all about your perception of time, and how fast it is moving for you. By traveling rapidly out into space and then coming back, (And by rapidly, I mean close to the speed of light) you could in theory age ten years while the world aged 1000. In that way, you could be "traveling in time". Sort of.

I remember reading something about the world's farthest time traveler, an astronaut who was in orbit for some time. I think he traveled about 1 fourth of a second into the future. Correct me if I'm wrong.

There is no way I can get into this thread -- a few friends of mine had a 7 hour conversation about this. 7 hours - and we took notes. And make diagrams. And woked out theories. And we concluded that A) If it ever was theoretically possible, we wouldn't be able to do it until long after the sun burned out. and B) If it ever WILL be possible -- there would have been evidence of it having been done[I.E. Someone from the future checking SOMETHING out.]. and C) If A and B were false and we DID figure a way to do it, it could only be a transferral of awareness, and not anything physical - and even that comes into question as the planet would likely be billions and billions of miles from the point you are at - moving in time but not space explains the basic thought. Even in the time it took me to write this -- counting movement of the galaxy, the universe, the solar system, and the planet -- We've moved over 15 million miles. I am not getting into the rest of our discussion, but suffice it to say - it's just not gonna happen.

i think time travel in either "direction" is 100% possible. but should we do it? i think not.

there are cartoons and movies and games about going back in time to "fix" history. if time travel were possible, its not totally unlikely that some ass will go back to Franklin and tell him that is he discovers electricity or something like that, the world would probably fall into perpetual termoil.

even for research time travel is a bad idea. same scenario as before: someone, even if it was an accident, will screw up the temporal pattern we all know and love, changing something is a possibly very durastic way. hell, its possible that someone could somehow prevent Halo from ever coming out!

Some one could not change what we already know becuase if they did we would have already seen the effects of what they changed.

If you ever read the HG wells novel "The Time Machine", the (false) science implemented there says that time is essentially another dimension to travel along; but this would make no sense, as human beings cannot physically slip through time.

Technically, Time Travel could land somebody or something in the same time frame as theirself, and that would not be feisable.

  • 10.11.2004 11:32 PM PDT

Um, time is another dimension. This is one of the fundamental ideas underlying Einstein's theory of Relativity. For example, the reason that you can't travel faster than the speed of light is because everything is already moving at the speed of light, through spacetime. If you are motionless in space, you are moving at the speed of light through time. This is why your perception of time slows down as you approach the speed of light through space. Similarly, photons (particles of light) do not travel through time at all.

To travel through time, you would have to find some kind of wormhole that connects you to another point in spacetime. It would be quite difficult.

Time travel is a paradox because if you travelled backwards or forwards you change history... So if you go into the past and change something, your world changes and you may not have been born, or your time travel device may never have been made, and if that happened what happens to you? If you never existed, you could never travel but if you didn't travel you would still exist... Paradox!!!

If you go forward you know how things will turn out and change history such that it won't turn out the way you saw... so either way you're stuffed!

Ever read Crichton's Timeline?

It's based on the theory, you can't do real time travel, but that there are alternate universes, and you travel between parallel universes where past events are currently happening.

Timeline is the only "time travel" story I've ever liked, a few outright "We realize time travel is bull-blam!-" stories aside.

Time travel IS possible. My friend flew to Iran a little over a week ago and is 8 hours ahead of us right now. I just cant convince him to send me the winning lotto numbers.....

We could just sacrafice someone and send them through a blackhole to find out if it goes anywhere ;)

I have deja-vu time travel. Which is when you do something and it seems you have done it the exact same way before.

Actually, I do believe that there is a way to communicate to the people of the future. As of right now, I have no proof of sending someone physically into the future, but my dad showed me something very interesting.

If we were to build COM structure that somehow manage to stay operational for 100 or so years, the people of the past can receive messages from the people of the future. It's a simple idea to think of at first glance, but then, once you begin to analyze how this could be done, it starts to hurt your head.

wormholes dont go anywhere, (they think) because the matter around one stops, like time stops nothing if anything could even get close with out freazing in time.

The movie was Planet of the Apes, in the begging they were going the speed of light, so a few seconds would be a few years for them.

Matter can't be destroyed, only transformed. So where does every thing go that gets sucked into a black hole?

I think it is possible to do, but I'm not sure humanity could handle it. Maybe a few chosen people. There are a ton of ignorant people out there and how do you think they would handle it?

I didn't mean it wasn't a dimension. D'oh.
