Far-Fetched Time Travel Concept Receives Private Funds 505

Posted by Zonk from the if-you're-going-to-make-a-time-machine-do-it-with-some-style dept.
WED Fan writes "A University of Washington researcher who couldn't find funds the old fashioned way has raised funds from private parties to continue with his studies of 'time travel'. He is studying the Einstein-Podolsky-Rosen Paradox. Basically, using spooky action, he wants to be able to use entangled pairs to send messages, not only through space, but also in time. 'As the evidence for this has accumulated, several fairly contorted and unsatisfying efforts have been aimed at solving the puzzle. Cramer has proposed an explanation that doesn't violate the speed of light but does kind of mess with the traditional concept of time.' Despite the implausibility of the science here laypeople have been inspired by the researcher's idea, enough to donate almost $35,000 to his project."

        it could be that you can't send messages back any earlier than the time the message was created, effectively only slowing time down so it take less time for the message to arrive. Less time could be no time at all so the message arrives when it's sent.

      Nah, it's not worth anything. If time travel is ever developed, the universe enters an unstable state. Stability isn't returned until a scenario occurs where time travel is never discovered in the first place.

        This brings up an interesting concept. Say you invent a machine to send a message back in time 20 seconds.

        So in testing the machine, you receive the message, and then in 20 seconds send it. It works! Great, but...

        On the second test, you start to wonder, "What would happen if I was going to send the message, but then change my mind when I receive it?"

        So you receive the message, then decide not to send it. Interesting paradox, huh?

        Either that, or the machine will always predict with 100% accuracy whether or not you'll push the button to send the message. So if you intend to not push it once you get the message, you'll never get the message. So there will be no way to "trick" the message into coming in.

        It's a bizarre concept. Thinking about it brings up interesting thoughts like whether or not we really have free will. :)

He wants to perform a relatively cheap experiment which should show whether his theory has enough going for it to be worth further examination. If these experiments fail, oh well, back to the drawing board.

    This is the way science is SUPPOSED to work. There's nothing wrong with being skeptical, but acting like this guy is a scam artist is ridiculous. This guy runs a super collider, yet everyone here is so damn sure they understand quantum phenomenon better than he does.

    I have yet to hear of any results, although I did have a strange experience the other day. I was about to try my first sip of Milo's Famous Sweet Tea when a 500 lb man appeared from thin air and knocked the glass from my hand before disappearing again.

    This is based on the Transactional Interpretation [wikipedia.org] of Quantum Mechanics.

    It's based on hard science, and makes testable predictions. TFS grabbed the most sensational lines from TFA.

    Some people think time is just a human construct...a way in which we measure the difference in the state of matter. If you think of reality as a motion picture of individual frames, time doesn't really come into the picture. Time travel doesn't make sense in this case because you can't actually bring everything in your near reality back to the state it was in before, never mind everything in the world, universe, etc.

    I can take a paperweight on my desk and move it 6 inches to the left, and then back 6 inches to the right...I've essentially caused the rock to time travel, at least on an easily observable level, because it's in the same easily observable state it was in before. On a quantum level, no...because various things have changed in the rock (the little bit of airflow from movement along with my fingers grabbing it and dragging it on the desk likely scraped some matter off).

    Anyway, just another crackpot way of looking at things.

    Disclaimer: I am a physicist working in a quantum information group, and have taken a graduate level physics course on quantum information.

    This won't work. The article doesn't give details, but by googling the scientist, I found this proposal [washington.edu], and immediately recognized the flaw in the experiment. He's trying to use a quantum eraser (wiki [wikipedia.org] of quantum eraser, and link [sunysb.edu] to good article on them) to change the image of the downconverted photons on a camera, but that simply cannot be done. The image on a screen can be changed using a nonlocal eraser, but only when you look at conincidences of the two photons. This is a common proposal for FTL communication, I just can't believe no one ever told this guy why it wouldn't work.

    The quantum eraser (linked above) can be pretty tough to get your head around. It combines interference, entanglement, and nonlocality, all tough nonclassical phenomena. Feel free to ask if you read the article and don't understand something.
