Time travel will never be possible.

[Wormthong]

ehm worm holes do not actualy make you go faster then the speed of light they just use literaly unimaginable amounts of energy to "fold" space so you aren't actualy going faster you just make the trip shorter or at least that is the general theory

 

[Wormthong]

well that is unless you call making yourself stop in "time" so you stand still in time but time around you still moves like in the movie time machine time travel

 

[mikecoulter]

Dr. Who seems to manage okay. I'm pretty sure with rules in place, one day it could be possible.

The hypotesis that time travel is impossible because otherwise we would be full of tourists from the future (Hawking), has several falacies.

First, it assumes it is impossible because we will never discover how to do it. There are several scenarios where that is possible, from mankind extinction to the science and technology evolving in an entirely different direction...

Second, it assumes people in the future would still be interested in tourism or stuff like that... Society can change over that point.

And finally, it assumes the timeline is one and universal (the "back to the future" way) but no one knows the true nature of timelines... There could be several, parallel, ones (the "dragon ball" way) or it could be a more personal timeline ("The Men Who Murdered Mohammed" way)

For anyone interested in time travel, worm-holes, unified field theory, and hyperspace I would recommend a book from Dr Michio Kaku entitled HYPERSPACE. It's a great read and covers a lot of questions raised by the man on the street. His writing is clear and concise, but best of all he doesn't treat you like a retard because you didn't spend years at university.

I was doing research for a story regarding hyperspace and a friend recommended it. I am no Einstein and feel very wary around science books written by experts. Why? Because they're often written for colleagues and other experts not once considering that Joe Public might want to see what's what. HYPERSPACE so impressed me, I bought a copy and it is a fascinating read.

To cut a long story short, check out his article: http://mkaku.org/home/?page_id=252

If you could travel through time, it wouldn't be called time. It would be called space. Then we'd have a space-space continuum, and that's pretty retarded.

Many physicists use that the proposition that space and time are interlinked or one and the same, so it's not really retarded. http://en.wikipedia.org/wiki/Spacetime. Sorry, got confused with what you said, anywho, argument still stands.

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?

Ok. This is simple to refute.

If Time Travel were to be invented sometime in the future why wouldn't they travel back to now and say "Here it is!"

This obviously hasn't happened. This is then proof that time machines cannot travel back in time to our time era.

However, this doesn't mean that time machines could never exist, ever.

It merely suggests that a future-invented time-machine would only be able to travel back as far as the microsecond after its invention.

So, you could have rampant time-travel in the far future (and probably Time Lords policing the use of the technology and trying to keep the time-line straight), but in our pre-time-travel era everything is just naturally linear.

Now this restriction could be a law of the Universe, or it could be the successful action of Time Lords, or it could be that everytime anyone tried to take a time-machine back (usually for mischief) someone would take another one back from an alternate universe to unify the fractured history of the metaverse into a single time-line again.

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.

No, that was a movie, actually. See? [http://en.wikipedia.org/wiki/Primer_(film)]

Erm... actually somone has already posted an article about this in response to my comment somewhere in this thread... its kinda, very much, happening... well, if he does makes a working one it is happening.

Can you find an article or something that he explains how he would travel back? I mean, what would happen? How would he get whatever back in time? And if he did, and he stopped 9/11, that'd be awesome Well, no... It's better we had it...but still, that'd be awesome

Couldnt go back to 9/11 anyway (even though stopping that would have been a better thing, no one would have supported the "reason" to go into Iraq without that), you would only be able to go back to the point when the machine was last turned on... So as it isnt even made yet you wouldnt even be able to come back to today.

This is ridiculous-I'm travelling through time right now, albeit forward.


What a farce.

Time is a Man-made measurement. You dont go backwards in it. At extreme speeds atoms vibrate slower. So your saying once you go fast enough, the atoms eventually stop vibrAting and the atomic clock ceases at lightspeed. And then once you go faster, the atoms.... Vibrate the other way? And somehow atoms that normally vibrate up-to down are vibrating down-to-up? Well they're still vibrating so the atomic clock time will start again. If you measure 'a day' bu sunrise to sunset, does time slow down in the summer and speed up in the winter? technically yes. Lets say your driving on the freeway at 60mph. So time for you is 1 mile=1 minute. If you slow to 55mph, did time slow too, since it takes a bit longer to go a mile? Or did your way of MEASURING IT slow? Lets say you slowed a bit because we used a sedative gas on you. So can we really say the more gas is in the car, the less you push the pedal, the slower time gets? No. Can we say the faster you go, the slower atoms resonate, the slower time occurs to you?
Also could you say time slowed down ONLY in the car but not anywhere else? It's the same with real time. We use atomic clocks because they are much more reliable than a car staying at 60mph. But if somehow solar radiation HYPOTHETICALLY threw off atomic resonance, can we really say it affected time? no. If it messed up our 'percieved time' we'd revert to some NEW measurment like sundials or quarts clocks. Time in the end is simply a man-made measurment that we can abandon if it doesn't suit us. It started when we started counting it, and it will go away when we stop keeping track. An apple going near lightspeed for 20 years will APPEAR like new, since it's atoms have slowed and the processes that go with it, but it's still 20yrs old. If ee counted time by constant physical decay, then i guess when they shut down constantly busy streets time stops for it because it's not eroding away as fast as the other busy streets, right?

If ya reply snip quote me so I get the message reminder.

When you think about it, we're all time travelling right now, at exactly one second per second, that being said, I do believe that there may be an infinite set of realities and universes, all which have different outcomes (varying from slightly different to extremely different).

This would lead to time traveling being available in one universe, but not available in other universes, and until we can find a way to travel to the other universes, we shan't have time travel in this one, due to the said fact that we can screw up our own universe by changing little things while going back in time.

*deep breath* phew, glad I got that one out. lol

One, we wouldn't have COD probably, and other games without, and other technology.
Two, what about a time machine to transport the other time machine into 9/11 so we can travel back to 9/11 with said time machine that we put in 9/11?
And, how is he going to do this? This man sounds crazy

There is no conceivable way to make a time machine like that... only the way they are making it appears to be fesable.

This has probably already been said, but...

If someone went back in time to change something then the consequences of that thing have already happened.

You cant change the past because it has already happened. If in the future time travel is invented and someone goes back to change something, it wont make a difference because its meant to happen.

The point is, if you traveled back in time you could do watever the hell you want
