As if Quantum Teleportation Weren't Spooky Enough, Physicists Propose 'Time Teleportation'

If this works, it would be awesome! We could send messages into the future.

But I don't quite understand the whole symmetric measurement requirement. "If the past detector was active at a quarter to 12:00, then the future detector must wait to become active at precisely a quarter past 12:00 in order to achieve entanglement". Concepts like "a quarter past twelve" only make sense because of the rotation of the Earth. So why, given its highly relative nature, does clock time have anything to do with this? If it's because of position, well, the Earth is in a different position at noon today than it will be at noon tomorrow, so it still makes no sense.

Will somebody please explain to me what the whole symmetric measurement requirement REALLY is?

-IMP ;) :)

Good ? That .25 til and .25 past caught my attention as well.

I went into the link and discovered that the quarter 'til and quarter past thing was just an analogy. It really has something to do with "conformal time", but no matter how hard I search, I can't find any explanations of conformal time online that are easy enough for a layman like me to understand.

-IMP ;) :)

Yeah, I figured that they were just trying to "dumb it down" for most people to get a tiny grasp on it.

is that a picture of... what i think that's a picture of?

my question is if they do actually link up times then could they send us a message back in time and would it have an impact on our future?

i don"t understand the part of the "same space" haw the partical can remain in the same space? every point referenced to earth is constantly moving throught space. galaxy movement+solar system movement+movement of earth around the sun and even earth rotation. to be in the same point in space is impossible!.

wow it is same like time capsule or a time locked e-mail message. if this could be done in the opposite direction it would become a time machine. other-wise if not the proccess it self it could be an ordinary thing.

I can already send messages into the future. By the time you are reading this I will have already walked clear away from my computer.

"Man, there's future *everywhere*."

Just wondering
Am not religious or anything but i have to ask a serious question here.
If quantum teleportation is possible (for humans a long time from now). I die on the spot right. Yes something on the otherside becomes a representation of me with my personality, memorys etc. but everything that was me is left behind. This thing might look and talk like me but i got made into dust right?

@ozz,

In the style of Dr. Emmit Brown:

I foresee 2 possibilities. One, we send a message back in time and remember to send the message to our younger selves at the precise moment that our future selves manipulated the entanglement of the photons and all is well. Or two, the photon does NOT get entangled at the correct moment which could either skew us into a different timeline or perhaps create a time paradox, the results of which could start a chain reaction that would unravel the very fabric of the space time continuum, and destroy the entire universe! Granted, that's a worse case scenario.

*Emmett

so you can only teleport to different moments of your live?

Or we could just play the song of time on a flute. It always works for Link from Zelda.

Awesome! We could send messages into the past and future!

TIME does not exist! What we call time is just a measure of relative physical existence. We exist only in the present. We can only measure our relativity by using another physical reference. Our mesurement of time is the relative rate of change between 2 physical masses using a 3rd reference rate of change that is; to the degree we can measure it, relatively constant and continuous. Such as the radioactive decay of Cesium atoms. This is the reason the speed of light is about as fast as we can go in or 3D universe. To go any faster would not allow a measurement because this will take us into the realm of pure energy which has no mass and thus no relativity. This is the realm of information. This is why quantun theory works becuase it is the transfer of information which exsists without relativity and can therfore be anywhere and due to entanglement can be reproduced in any relative position. We will detect this transfer of information as teleportation.
But we can still only measure or see this transfer of information in our present state or the detectors present state of existence.
In other words time is the constant exchange of information throughout the universe.

wow i agree with you/

i have the same intuition i will call it.
that if you for example dismantle me into atoms and than teleport them to other point in space and than just put them together into me again. i have a feeling that it won"t be me the new me in the other point will be able to act just like me but it won"t be me. for example take an equal experiment. instead of dismantling the real you. we will only make a copy of your every particle and send them like the first time.in this case you will remain the same man but who is the other? he is an exact copy of you. but may be all his memories are yours. but you share diffrent consciousness. the first teleportation is exactly the same but with destroying the original after copying which means killing the original entity yourself. it is very hard to grasp but may be what makes us conscious is a some kind of soul which is unique and our brain and body is just a medium.

So we will have a perfect world actually?

I looked at the paper on this and I saw so MANY equations my eyes went cross. HA! HA!

What Is Science but A Continual Lesson of The Challenge To Studying The Entire Known Existence of Everything.

-Truth-

though the actions of the material are interesting, the proposition from popsci is rather retarded.

its no more useful for sending messages to "the future" than an envelope that says "don't open till x-mas".

It would be nice if I could get someone in the future to send me a message of what the Mega Millions winning numbers were each week. That would be awesome!

@marco: It would be slightly more useful if you send a gift to the future, as the recipient will not be able to find it before the time he's supposed to get it. Why bother hiding the gift when you can just make it not exist for a while?

Could this be developed into a data storage by suspending data in a "void time" until retrieval? Essentially send my data into the future of when I retrieve it. Because of the time travel effect I would receive unaltered data.

If this technology is going to work the future must me insanely tired of messages from the past.

@orangebloodedal
"... time is the constant exchange of information throughout the universe."

That's very perceptive. Not many people appreciate that, and you are almost correct. In practice, it's a lot more complex because there are a lot more dimensions to take account of than are generally considered.

I realised this when I caught on as to how the spirits who work through me when I'm healing people must coincide with this space without being in this space, there is another, coincidental framework adjoining ours. Somehow, and I wish I understood the physics, I can access this other side. I see dead people. Once, I was scolded for not properly preparing to work, it was a little old lady and she was annoyed. I always prepare properly now, can't take being scolded by dead people.

Great thread. I wish quantum mechanics was not so hard to comprehend!
Cheers,

I enjoyed reading the note about time not existing but being a mere perception, but I'm not sure I agree that it doesn't exist. I can see where you're coming from on that. But there's supposed to be some kind of particle that travels backward in time. Even if that's not true, time is part of so many physics formulas. And if time doesn't exist, then Einstein can't be right about it being relative. If time is merely perceptual then the exchange of information would be constant. I guess you could say that the curvature of space affects the rate of info exchange. But for a rocket that travels at near the speed of light, it's not the curvature of space that makes it travel more slowly through time (or our perception of it). It's just that speed affects the observance of time for that object.

I want you to be right, because I want Einstein to be wrong so that we can reach other solar systems in a human's lifespan rather than there being a 'speed limit' and the whole infinite mass thing. So hopefully everything I just said is wrong. lol

Thoughts?

Einstein was correct. All physical properties of matter are relative. It is the delta in the relative states of matter that intiates the deltas in the continuous exchange of information. This change in information is directly related to the change in relativity of the matter being observed. Therefore time is relative.
Einstein says as matter approaches the speed of light its mass increases and this relates to a slowing in the relative flow of time with reference to another observer. I say as matter approches the spped of light it starts to take on the characteristics of light because the relative posistion of these two masses are being changed at a rate resembling that of a single photon. He is right. The energy to do this would be astronomical. This matter will not increase in mass but its information exchange rate will approach that of pure energy which is zero(pure energy is information).Time will appear to have slowed between these two masses which are changing relative positions at deltas approaching the speed of light(electromagnetic radiation) which is as close to pure energy our instruments can measure at present. Since you are only adding energy to one body, this mass(let's say a starship) will appear to have slowed down in time relative to the other mass(Earth)who's energy levels remained constant.

okay,

The most shocking tidbit of information in this whole article is not really about time travel.

The article says "But researchers have already achieved teleportation across space in the lab"

Am I late to the party or what,,
Shouldn't this information be generating major news coverage.

Do we actually have the ability to teleport, even if it's just across a lab.
If I am reading this correctly - that is incredible news.
right up there with "invisibility"

@KamaKwz,

Yeah, you're a bit late to the party. Teleportation is old news and it doesn't get much coverage in the news because journalists aren't anywhere near as interested in that as they are in Snooki. Sad but true.

@andromeda324, the "soul", the "person", the "individual indentity" are abstractions. They have no physical existence as objects in their own right, they are merely information abstractions implemented on the hardware of the body and brain, Like programs, data, and running processes on a computer.

what happens to the programs and data and processes when you physically destroy the computer? Or, to paraphrase one perceptive slashdot reader, say you build a house out of Lego, and keep it for a while. A few days later you take it apart and put the bricks back in their tub. Where did the house go?

I think you know the answer.

@ReincarnatedMan, it's unlikely you will ever be able to understand any kind of physics properly as long as you are the type of person who believes you can see dead people. Since dead people have no physical basis for existence, these are two distinct and entirely incompatible belief systems.

@orangebloodedal, you were doing fine with your explanation until you said:

"This is the reason the speed of light is about as fast as we can go in or 3D universe. To go any faster would not allow a measurement because this will take us into the realm of pure energy which has no mass and thus no relativity."

Which is just a load of meaningless mumbo jumbo.

You clearly ran into the limits of your understanding, this is probably because you "learned" Special Relativity on the Discovery Channel rather than in college. I really don't think you should be trying to explain it to someone else.

Par for the course on any popular science website, I guess.

@alias007, your posts are the most coherent in this thread and the least contaminated with bogus pseudo-science. Well done, but hanging around here clearly poses a serious danger to your intelligence.

Everybody else: the only road to understanding advanced physics concepts like Special Relativity, General Relativity and Quantum Mechanics is via the mathematics - no human metaphor will ever be capable of expressing these theories properly because human metaphors are confined to the classical world. It's like trying to describe a rainbow with only a black pencil.

If you want understand one of these theories, get a first year college textbook that offers a proper mathematical treatment of it, and once you've worked your way through that, let it ferment in your head for a few years.

Time teleportation won't happen.

First line of their published paper says: "The quantum vacuum is theorized to exhibit a variety of thermal effects associated with spacetime horizons..."?
Physicists' "understanding" of spacetime is flawed. We have to go back to when this "spacetime" concept appeared (it was based on Einstein's 1905 "special relativity") to understand what went wrong.

There was a lone highly-respected physicist who suggested in mid-20th century that Einstein's derivation od special relativity's equations was based on unstated assumptions and thus could be wrong. Why didn't they call him a nut like they call all those who suggest that special relativity has problems. Well, for one this physicist had a Nobel prize...You can read his quote and details at http://www.physicsnext.org.

Actually bagpipes, you sent your message from the present to be received in the future.

It would be useful for storage of information I would think if you can get past the precise moment to open thing but I would imagine a repeater of some sort would be useful to store data in nonexistence is the most mind boggling thing I've heard of but it would allow for much much faster data access if you are streaming data through time at rapid intervals and you're only limited by how small you can get those time intervals... Or you could upload an entire archive of human history to be accessed and added to regularly seems a bit more useful than a don't open til Xmas letter if you ask me ecspecially if Christmas is 65 million years down the line :)

The Sixth Sense - New GROUNDBREAKING Book in 2012! The Sixth Sense leads to Enlightenment
DNA Healing Code - Hardwired in ALL Humans

As an example of what I mean by “Groundbreaking” info that can be found in the 2012 release of my new book on The Sixth Sense (not yet titled )…..
There is a sequence required to communicate with Infinite Intelligence – to gain insight and/or much more complicated yet achievable, HolisticDNA Energy Healing. The sequence required is on multiple simultaneous levels, not just “step by step” like an instruction manual for assembling a piece of furniture.
The “Key” sequence has to do with applying known facts, beliefs, emotions and faith (not religious) – if not applied exactly as detailed, the Sixth Sense will remain dormant, and not be “activated”. As an example:

fact --
fact --
fact --
belief --
fact --
in theory --
belief --
fact --
belief --
Faith --
fact --
fact --
fact --
Faith

you won’t find this in any existing text, which is why The Sixth Sense is so rarely utilized and hard to confirm. This will allow the Scientific Community to experiment and confirm my claims — remember, just a few decades ago, it was impossible to have a Man walk on the moon. Time for the next impossible to be challenged and confirmed — real

Remember the three investment bankers from Connecticut that bought one winning lottery ticket. They won a hundred million+ dollars. What is the first thing you would send if you could send a message back from the future to the present? Winning lottery numbers obviously!

"It would be slightly more useful if you send a gift to the future, as the recipient will not be able to find it before the time he's supposed to get it. Why bother hiding the gift when you can just make it not exist for a while?"

Does that mean I could send someone a gift into the future and while that person is sitting there the gift will pop into existence out of thin air?
There is a Santa Claus after all!
