Some guy just invinted a Time Machine based on Einsteins theory.

[RedShoe]

I don't quite understand how it works. He explains it, and the setup looks simple. It's a bunch of lasers. But... how does it actually send something back in time? Do the lasers help the object gain speed? If so, once that object reaches light speed it disappears? How do you calibrate a time in space in which the object lands? What if the moment you turn it on you get a message from the future that says "TURN IT OFF!!!"

The idea that time travel to the past is only possible in the future is cool.

...One significant limitation of such a time machine is that it is only possible to go as far back in time as the initial creation of the machine;[15] in essence, it is more of a path through time than it is a device that itself moves through time, and it would not allow the technology itself to be moved backwards in time. This could provide an alternative explanation for Hawking's observation: a time machine will be built someday, but has not yet been built, so the tourists from the future cannot reach this far back in time.

[tical]

wow what a trip

[grumpy]

if it works, we would have known already.

[TBrown]

There's a lab in Switzerland where they can teleport electrons...so I guess teleportation will be possible sooner than time travel

[D]

Neat.

Of course. none of these "time travel to the past is only possible in the future" concepts are taking into account the possibility of using naturally occuring phenomena (such as black holes) as the catalyst for temporal travel.

[BucksMania]

interesting, very interesting

[Stephen McTowelie]

Think i saw a program on tv about this and they explained that its kinda like having a phoneline to the future once the time machine (laser chamber thing is built you can talk to the future)
Hurts my head thinking about this though its too early.

thats sounds creepy to me.

[Stephen McTowelie]

Yeah is a little creepy especially if you were to talk to your future self !

[en21]

Can I borrow it for 5 minutes.. I need to go back and buy www.sex.com

[sweetpurple04]

where is the money shot

[Screaming]

thats cool stuff man

[grumpy]

if you can travel in the future but not in the past you will never make it back.
If there is a time machine evented ever, we would alreday have known about it.

These two lines kill the timemachine forever.

Objections (wikipedia)

In a recent paper by Ken Olum and Allen Everett[1] the authors claimed to have found problems with Mallett's analysis. One of their objections is that the spacetime which Mallett used in his analysis contains a singularity even when the power to the laser is off, and is not the spacetime that would be expected to arise naturally if the circulating laser were turned on in previously empty space. Mallett has not offered a published response to Olum and Everett, but in his book Time Traveler he mentions that he was unable to directly model the optical fiber or photonic crystal which bends the light's path as it travels through it, so the light circulates around rather than moving in a straight line; as a substitute he chose to include a "line source" (a type of one-dimensional singularity) which would act as a "geometric constraint", bending spacetime in such a way that the light would circulate around on a helix-shaped path in a vacuum.[2] He notes that closed timelike curves are present in a spacetime containing both the line source and the circulating light, while they are not present in a spacetime containing only the line source, so that "the closed loops in time had been produced by the circulating flow of light, and not by the non-moving line source."[3] However, he does not provide any additional argument as to why we should expect to see closed timelike curves in a different spacetime where there is no line source, and where the light is caused to circulate due to passing through a physical substance like a photonic crystal rather than circulating in a vacuum due to the curved spacetime around the line source.

Another objection by Olum and Everett is that even if Mallett's choice of spacetime were correct, the energy required to twist spacetime sufficiently would be huge, and that with lasers of the type in use today the ring would have to be much larger than the observable universe. At one point Mallett agreed that in a vacuum the energy requirements would be impractical, but noted that the energy required goes down as the speed of light goes down, so he argued that if the light is slowed down significantly by passing it through a medium (as in the experiments of Lene Hau where light was passed through a superfluid and slowed to about 17 metres per second) the needed energy would be attainable.[4] However, the physicist J. Richard Gott argues that slowing down light by passing it through a medium cannot be treated as equivalent to lowering the constant c (the speed of light in a vacuum) in the equations of general relativity, saying:

One has to distinguish between the speed of light in empty space, which is a constant, and through a medium, which can be less. Light travels more slowly through water than through empty space but this does not mean that you age more slowly while scuba diving or that it is easier to twist space-time underwater.

The experiments done so far don't lower the speed of light in empty space; they just lower the speed of light in a medium and should not make it easier to twist space-time. Thus, it should not take any less mass-energy to form a black hole or a time machine of a given size in such a medium.[5]

Later, Mallett abandoned the idea of using slowed light to reduce the energy, writing "For a time, I considered the possibility that slowing down light might increase the gravitational frame dragging effect of the ring laser ... Slow light, however, turned out not to be helpful for my research."[6]

Finally, Olum and Everett note a theorem proved by Stephen Hawking in a 1992 paper on the chronology protection conjecture,[7] which demonstrated that according to general relativity it should be impossible to create closed timelike curves in any finite region that satisfies the weak energy condition, meaning that the region contains no exotic matter with negative energy. Mallett's original solution involved a spacetime containing a line source of infinite length, so it did not violate this theorem despite the absence of exotic matter, but Olum and Everett point out that the theorem "would, however, rule out the creation of CTC's in any finite-sized approximation to this spacetime."

i have read plans that they are building the space station just so they can build a huge spaceship called Vanguard...whcih will go out to Alpha Centauri...it will be a generational ship...as they will be gone for like 50 years or more.

anyway the reason for going is simply to conduct experiments with space warping....no one wants to try it near earth

[Nysus]

There's a lab in Switzerland where they can teleport electrons...so I guess teleportation will be possible sooner than time travel

Teleport electrons? Are you sure it isn't the quantum photons that they are able to switch the state of one where it changes the state of the other instanteously? Otherwise link?

Yea, I want to see the link to where they say they can teleport electrons. light photons Ive heard but electrons?

[Nicky]

What about if the time machine has not been invented yet, and you can't travel longer back than to when it's invented?

[nico-t]

We should have peeps walking around from the future in present time if there would ever be a time machine. So it's never gonna happen.

what we call aliens are really incredibly evolved humans that come back from the future..it's real, believe it

[Goodings Media]

why would you want to mess with time?

Shit happens for a reason. Let the shit be.

Now 3 sea shells to clean my ass, THATS what I want invented.

(...who's seen the film? )

Yeah well lets hope we dont go all demolition man i fucking like swearing !

Oh and you cant kill off the time machine theory with if you could do it people would be here already !

The time machine or theory in question can not physically make you go forward or back in time just lets you communicate through the machine to the same machine in a different time if that makes sense !

[jryan89]

lost in space!!! we're all gonna die.............

[Stephen McTowelie]

Oh and if it does work as soon as its turned on he should hear voices now this really hurts my head
maybe we could get a sports almanac off biff from the future

[D-Money]

So this time machine really doesn't let you travel into the future.

It's more of a "past" travel machine.

From the point it was turned on. So really, the most effective use without killing people over it, in the future, drop notes to us in the present (their past) on what mistakes not to make in our future.

Like, don't vote for Bush, oh shit, we're too late for that one.

Anyway, interesting find. I myself like tooling around with laser technology in the garage on my weekends.

[Michaelious]

Dont really understand the time machine thing but go back and get rid of Prezzie Bush!

[NinjaSteve]

Shit, I knew lasers would come in handy someday. Now where did I put mine...

[SCtyger]

what? no mention of tri-lithium crystals? hogwash!

[Verity]

Yea, I want to see the link to where they say they can teleport electrons. light photons Ive heard but electrons?

yeah, I'd love to see something on this too!

screw time travel, teleporting is exactly what I need

[Phoenix]

Shit, I knew lasers would come in handy someday. Now where did I put mine...

you still need a flux capacitor and a slingshot from the sun

[RedShoe]

if you can travel in the future but not in the past you will never make it back.

Both were answered in the video. Thanks for watching.

Actually. The wosrt thing the future can do is 'warn us' of shit. Think about it. What if in some tiny way Bush being president somehow caused this guy to think in a direction that led him to build the machine. Changing one tiny thing based on the future may alter the future in a devastating way.

Didn't you see Back to the Future II?

[The Duck]

I dont see how that machine will ever work.

woah! after reading the article, it's never impossible that someday we will be asking... "what era would you be visiting this summer?" or "chics in 1820 are hot, try 'em!" hahahaha that would be nice...

[rob34]

Black Holes swallow light, And everything else. You cannot use a black hole. But you can use a worm hole.

Was that the one with the guy in the time machine where he'd have to hide out in a shipping container while he travelled thru time? Or something like that?
