Time travel will never be possible.

[BaronXS]

Because if it WERE, the public would eventually get their hands on it, which means millions of people would have the ability to change history to their will. Now, eventually, some idiot/crazy person/terrorist is going to go back in time to where the first humans were, and kill them, or something along those lines. That would cause a major paradox, seeing as the killer's ancestry line would never exist. So as long as the universe as we know it isn't destroyed, we can be certain that time travel will never be possible, at least for humans.

This isn't the only example to prove my point, there are an infinite amount of possible paradoxes, thanks to the butterfly effect.

Your thoughts on this matter?

Unless they go by dragonball/terminator rules where when you time travel back you create an alternate timeline.

 

[AkJay]

welcome to common sense.

I'm going with the impossible paradox' possible from time travel, you know some fucktard owuld mess it up at one point.

 

[Taerdin]

It depends on what philosophy of time travel you subscribe to... if you assume theres only one timeline then sure but what if there were parallel universes :O

I also think its lame saying things will never be possible. Theres a lot of things people from 300 AD wouldve never thought possible that we have now... its hard to say but likely we won't be alive long enough for your claims of impossibility to be proven wrong

 

[BaronXS]

Oh it will be possible at one point, and than someone will use it to fuck up the space-time continuim.

My point exactly.

Isnt a guy making a time machine that can take you to any time between the present and the time that the machine was switched on? And if you switch it off and then on again, it would be reset.

I heard the guy talking about it a couple fo years ago, it was interesting.

I've had this exact theory in my head for a year now

 

[LilGherkin]

For all we know some guy traveled back in time to assassinate the guy that created the time machine. Wait a second... If he kills him than there's no time machine for him to use to kill him... Why Paradox, why!

 

[Sir Ollie]

Time is a invention of man, why change it?

You mean like a video camera?

 

[Taerdin]

of course time travel is possible, we already travel through time perfectly well.
in one direction.

WINNER!!! [http://www.youtube.com/watch?v=jDRfCThm6IM]

I'm traveling through time right now actually, its pretty awesome...

 

[barryween]

I would think that just going back in time would fuck everything up. Not even in some like, weird big chain of events sort of way, just that going back in time, even for a second or 2 would just mess everything up.

I will cite Samurai Jack...
Aku you dirty bastard...


But seriously? Going back in time would create a new universe, so it wouldn't matter anyway.
Catch my drift?

 

[LongAndShort]

What if travelling back in time and doing something is actually part of the timeline and them not going back in time fucks everything up because they didn't do what they needed to do... like in Doctor Who, when he goes back or forward in time preventing aliens and stuff from messing up history.

 

[Sieg The Bum]

It?s not only possible but it is being done (On a very small scale).

According to the general theory of relativity time is relevant. So without going too deep into the finer details, the faster you go the slower the time flow. This has been tested by shooting decaying particles at speeds close to the speed of light. They then measure the particles to find that they didn?t decay as fast as they should have thus proving that the particle experienced a decrease in time flow. The next big step that has to be taken is to make it so a person would be able to go that fast and survive it but they would only be able to travel forward in time and not back.

So what happens to the time traveler? He just disappears from the face of our universe? And what happens to US when our space-time continuum is fucked?

 

[The Blue Mongoose]

The Science of Discworld had some interesting stuff on this. Basically the only way to travel back in time is to travel at a speed greater than the speed of light, this means using wormholes (which may or may not exist). And also you could only travel back as far as the creation of the time machine.

Some very clever mathematicians recently proved that if it were possible to travel back in time it would be impossible to change the future, I thought that was an interesting argument because causality is always a big sticking point with the whole time travel thing! So that kind of blows your idea out of the water a little.

They still haven't proved time travel possible or impossible.

p.s I'll try and find a link to it.
