time travel, is it possible?

[Arkady Rossovich]

trying to find the article, but a few years ago the world of science was rocked by a team of scientists who successfully sent lihgt particles backwards in time. they went something like 1/1000th of a second or something like that. It was recorded using one of those nano second cameras that capture like a trillion frames per second.

They did this by putting beams of light into a particle accelorator to make them travel faster than the speed of light. They woud put them in one end and make them emerge from the other end afterwards, or in this case prior to.

The beam of light would emerge from the one end, before it was even inserted into the other end.

Obviously traveling to the future is possible, since were doing it right now, and astronauts have done it at even faster rate. but now it's also been proven that you can travel back to the past.

I suspect that the reason we aren't being disturbed by tourists from the future is simple.

A. we annihilated ourselves before we developed the ability to do so
B. It requires mega resources, that only the government can come up with, and our future leaders are extremely opposed to it. most people would be. you make one tiny change in the past, and you end up never being born.

C. Maybe we are being visited and we just don't know it.

I have never heard of that breakthrough with scientists and light.But as for travel itself i would guess its either be a or c.A is ovious,but i have heard some theories about c.

Like one example is they could already be here,but are not allowed to say anything.Like you could walk down the street,and barely notice the guy walking next to you.He could be from the future,or those bunch of tourists you see could be a group from the future seeing how we live.

I look "a spastic," huh?

I'm still not very convinced that it is yet possible. You gave me a bunch of theories Einstein had. Not that he was an idiot by any means, but like he even proposed, they're theories. I've yet to see any proof of them.

Well we can blast you off into space, if you want. They're theories that have been 'verified experimentally' by some of the most brilliant minds working in science. What do you do for a living?

EDIT: Hang on, are you disagreeing with Einstein? LOL!

So thats who this dude is.....

lol, coolest thing I've seen in days.

I'm simply saying that I'm pretty sure he had theories, not actual experiments, with this particular subject, and that I currently have yet to hear about or witness any of these experiments, as well as their outcomes.

As for what I do for a living, what does it matter? I know I'm not a scientist, and I know I very well may be wrong... But I'm fairly sure that people are not blasting themselves back into time, similarly to how it was done in Back to the Future... Which I've been under the impression that this is the subject matter that was brought up.

Regardless of whether or not that kind of travel is possible, I teach martial arts and attend college. However, it doesn't take a certified genius to truthfully say, "I can't get to the 1800s."

The experiments have been performed, though. One experiment has been to fly atomic clocks in planes around the Earth in opposite directions. The difference in time between the two clocks after the flights was consistent with those predicted by time dilation.

I too don't discount the possibilty that it may all indeed be nonsense, but by the same token I would never discount the notion that it is theoritically possible, without resorting to "I'll believe it when I see it"

People are discussing the quantum physics and theory of relativity in questioning whether or not you could travel through time, but how would you physically do it?

How is it possible to build a machine that could travel through time out of metal? What exactly are you going to use to break the timespace continuum (or what have you) ? What combination of gears, bolts, nails, metal, and whatever else you have lying around is actually going to travel through time?

Time travel is not possible. Unless you are referring to your own slow journey into the future.

Oh, and some guy on This American Life said you could build a time machine, but only travel back to the time you flipped the switch? So when I flip the switch on my time machine, I can travel back to the time when I flipped the switch? Wow. That's amazing.

Well, if you could do that, it would actually be quite possibly the most amazing thing ever in the history of mankind.

No, you don't get it. It CAN happen. When you flip the lightswitch, you instantly travel back in time to the moment you flipped the lightswitch. I can build a time machine out of a shoebox and strings if that's all it can do.

 

[Fried Gold]

Okay, at the risk of betraying my cool exterior exterior, I'm just gonna say... I don't get it.

 

[Bat Attack]

Whats that film, or book where people time travel but the end up reappearing in space by accident?

 

[Bat Attack]

BTW, I think time travel would be horrible, you would have people going into the past and screwing up the future, ending peoples lives, possibly even ending the world.

 

[Carcharodon]

no no, I'm pretty sure it was called "college advanced physics class"

god dang i'm surprised you all havent heard of relativity before

I have, but it involves travelling near or at the speed of light; nothing can travel faster than the speed of light, according to relativity theory.

 

[The Man Of 16]

Yes, but the Christians think its blasphemous, so thats the only reason theres doubt.

Same with stem cell research, you can still do experiments on embilical cords AFTER the kids born. And can someone remind me why we cant do experiments on stillborn kids? Or miscarriaged babies?

 

[Bat Attack]

Yes, but the Christians think its blasphemous, so thats the only reason theres doubt.

Ehh, most "hardcore christians" (aka bible thumpers) don't even believe in black holes, true?

 

[The Man Of 16]

They dont really contribute much but their opinion. So I'm guessing that they only believe in what they can sense. Everything else is the DEVIL!

Going into the future has to be impossible, the future is not set. Going back would re write present and stop us from going back to the future.

Aren't black holes only a really plausibly theory at the moment anyway? I don't think we've seen them yet.

Even some of the greatest minds in the world said that Wormholes were possible but today they are things of sci-fi.

 

[Noir]

ok heres what i think, if time travel were possible than wouldnt someone from the future be visiting our present time to tell us or show us that its possible?

...Okay, this is why it never happens your hypothetical experiment would create a paradox.

Also, time travel happens all the time in the quantum world anyway. Electrons comeout of black holes before they go in, time travel can happen, if it can happen in the macroscopic world we'll probably never know.

Mmm, actually most physicists agree that going back in time is impossible but forward in time is possible, but the ammount of energy required would be impossible to muster and control, for technology as we now know it.
Or, that's what I heard a physicist on PBS say.

Well going into the future would be easy as long as you can cheat. Suspened animation... You'd wake up and it'd feel like you'd travled in time.

 

[Mantis Rapture]

Okay, at the risk of betraying my cool exterior exterior, I'm just gonna say... I don't get it.

You build a 'time machine'. (The machine he's talking about would be some lasers slowed down andforced into a loop bending time and space and **** - the machine dosen't travel though, just whatever you put into it)

You turn it on at 7:00, june 12, 2007. That means the earliest point in time you could possibly 'travel' back to is the moment you turned it on, no earlier.

Theorieticly, as soon as you turn this machine on, you should be getting messages from the future - from 'tommorow' until the moment the machine is finally turned off.

From what I remember about this machine (that they are/were/will be actually building) physical objects won't be able to pass through it though, only messages (radio waves, **** like that) - but theoreticly future, upgraded, versions of machine might be able to actually send objects and, maybe, people back.

Or something.

actually the faster you go and the closer you are to a massive object your time goes slower than someone who isn't.

If you go at even half the speed at light and buzzed around for a year, two years would have passed on earth, but one year would have passed for you.

If you lived on a planet orbiting a Neutron star one week would pass for you but a million years would pass on earth..

General and Special Relativity prove this of course.

 

[Exabyte]

Theoretically yes, via a worm hole in the universe.

 

[Rorschach II]

ok heres what i think, if time travel were possible than wouldnt someone from the future be visiting our preasent time to tell us or show us that its possible?

The two possible solutions for this is that 1) There are time travellers among us who choose to remain anonymous (or perhaps that explains UFOs?) or 2) When you travel through time, you go to a parallel universe as to protect any paradoxes from happening in your own and destroying the fabric of space-time.
