is time travel possible?

[MagicRat]

Time travel has been mathematically proven as possible.
However, our theoretical understanding of the nature of the universe and the mathematics used to support these theories is flawed, at least in that it is incomplete.
So right now, all I know is that there is still so much exploring and learning about the nature if the universe to be done.
If time travel did become possible, it would be like the discovery of the atom bomb; a terrible weapon, for which human nature is not ready.

I agree with Magicrat, the world would fuck itslef over if time travel was possible.

Some underground time travel would probably happen, leading to crazy businessmen going back in time and buying stocks

in case you missed it is immpossible for anything with mass to accelerate to or past the speed of light. and wormholes would not bring you to the speed of light, infact wormholes have nothing to do with speed, all they do is decrease the amount of distance from one point to another, like if i wanted to be in my kitchen right now i would have to walk about 30 feet, and what a worm hole would do is make it 1 foot.

and i would like to see where it was proven possible, i find it highly unlikely that is has.

[moslerporschefreak]

Because I do not have an advanced degree in mathematics, I cannot say definitely whether or not it's possible. What I do know is this. Developing a theory of time travel would be akin to non-Euclidean geometry. Simply because it wasn't known for a while doesn't mean it isn't possible, I mean, parrallel lines can intersect (think of longitude).

However, the theory described by several physcists is very flawed. They basically made an enormous jump from a photon detector test to a multiverse theory. The idea of alternate universes has yet to be proven. Also, would traveling faster than the speed of light really let you travel back in time or just see the past. There's a huge difference

[MBTN]

I thought traveling at the speed of light would put you in the "future" so to speak. You wouldn't age like everything that isn't traveling light speed.

[loismustdie]

no, theoretically travelling as fast as the speed of light would stop time,and travelling faster would reverse it, and mulitple universes is implied by string theory but there is no way to proove it, but there is no way to prove string theory. think of it this way our universe is a slice of bread in a loaf of bread, and the other slices of bread are other universes, again can't be proven.

let me say this one more time IT IS IMMPOSSIBLE TO TRAVEL BACK IN TIME, OR TRAVEL INTO THE FUTURE, (when i say in the future i mean faster than we are traveling through time(time dilation)).

[moslerporschefreak]

Theoretically, if you travelled faster than light, you would actually travel backwards in the space time continuum or would you simply be able to view the past?

Also, off topic but loismustide, is your screen name in reference to Family Guy? if it is, more power to you.

[loismustdie]

of course its from family guy, i mean its only the best show ever

stewie rocks

[moslerporschefreak]

Rock on

Well, you know that Stewie once made a time machine, so maybe if we were all animated and the laws of physics didn't apply...

[integra818]

What the heck is a wormhole and WHERE the heck are they?!?

[loismustdie]

wormhole, lets see, say the universe is a sheet of paper, now put two dots on opposite sides of the paper. what a wormhole would do is "fold the universe" so to speak, so the two dots are on top of each other, and the distance between the two points is dramatically decreased, like from millions of miles to a matter of inches or centimeters.

[loismustdie]

well, none has actually seen them, but they have been proven to exist, so i guess noone knows where the hell they are.

[Integra06]

Even if we could go back in time and it was possible to alter time, some idiot would go back and change an event that, in the future would cause him to never need to go back in the past in the first place.

The basic point is that if a person goes back in time to keep "Event B" from happening, he would need to change "Event A". Once he changed "Event A", he would have had no need to want to change "Event B" in the first place, so "Event A" would remain unchanged.

[moslerporschefreak]

Loismustdie, we know what they are, we've proven that they exist as you said. We just haven't figured out how to see them or use them (like we ever will be able to). I could be wrong, but since wormholes are two sided black holes, the shear gravitaional pull on even the event horizon would destroy any material being transported across, let alone the sphagetti affect that would occur towards the center. Not only would you be stretched going in, but condensed at the center, and restretched in the opposite direction while leaving. Nothing could survive those forces.

[moslerporschefreak]

Also, Integra, there's a name to the paradoz that you mentioned, I'm not sure of the name, but I'll ask around about it, I know some people who very well might know.
