Time travel will never be possible.

[Lordmarkus]

Well, if someone managed to travel back in time we would know it. Though in this time universe, Hitler never was killed so I guess it will never be invented.

Though, no bombs fell during the Cold war... Idea for new conspiracy theory - writning down now...

 

[oliveira8]

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

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?

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 time traveler would possibly be stuck on the new space-time continiuum, while us live our lives perfectly fine in the time traveler original space-time continiuum.

It's not that hard to get.

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?

If time travel was possible we are now living in the result of any time travel. Therefore all time travel (if it ever happens) is part of our history and we can't change it.

So you're saying that if someone went back in time that it would have absolutely no repurcussions on our universe?

 

[Pendragon9]

I'm already time traveling too. I can accelerate through time thanks to my invention "the mattress of time travel".

You lie in it, you travel 8 hours into the future.

 

[Inconnu24]

'Time' is a system of measurement created by human beings used to give us a sense of structure to the references/memories in our minds that we call the 'Past' and ideas we call the 'Future'. My point being: the past and future don't exist outside our minds. Therefore, physical time travel is impossible.

 

[Macgyvercas]

it's possible to kill your ancesters, but only if you have a paradox machine to hold the paradox in place (Doctor Who reference)

So you're saying that time travel will be possible, and will NEVER be misused in any way so it causes a paradox, be it by accident or on purpose?

 

[Kinguendo]

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.

You mean like a video camera?

No, thats not even nearly what I said... anyway, no it can put you back in any time between now and when it was turned on... like a reset button if you screw something up in the day.

EDIT: And by "it can", I mean that is the intention once it is made.

 

[Sigel]

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.

You just blew my mind. O_O

If by traveling in time you create a different line of time and space, there would be two different space-time continiuum. The original and the one that the time traveler created. The more he travels the more alternate universes are created.

What would most likely happen is that the Time Traveler could never come back to the original universe.

 

[Triforceformer]

Well if we do, It might be like Bender's Big Score where all Paradoxes become resolved by dooming any clones and stuff to death.

ours won't be, we will observe his disappearance and if he returns it would make another universe where he returns. He would never be able to return to his home universe truly, since he'd make another universe upon arrival.

I just hurt your mind with logic... didn't I?

Huzzah! Someone else thinks this too!! I'm not crazy after all!

If someone did screw up history than it would have already happened and would be accepted as part of world history.

 

[lostclause]

Not necessarily possible, this is an 'if it is' situation.
It can't cause a paradox that doesn't exist today e.g the grandfather paradox. Can't say it won't be misused but the end result will be the world today.

 

[Mjolnir07]

This is easy, if time travel is EVER in the future invented then there would be an infinite number of people in all instances of time traveling backwards. If it were ever to be possible and then someone found a way to do it people would be telefragging eachother 99 a second like in Quake.

Does noone here understand quantum physics?

Nope, that made sense, but that's also proving my theory in a way. We could never travel back in time in OUR universe. We could go back into a DIFFERENT universe, if your theory is correct.

This would allow a person to travel to distant planets without worry of aging and dying on the journey. The energy needed to move something as big as a person (or bigger) would be immense and we do not currently have anything with that type of output.
*musing*I wonder if its possible to warp places?
