    It's only subatomic particles (sorry no real life Doctor Who's yet ) but it could be possible



    http://www.physorg.com/news63371210.html


    I saw a documentry about this guys theory and it sounded pretty solid, Something about Gravity affecting time, and mass affecting gravity, and light affecting mass therefore light affects time



    thoughts? I posted here and not psuedo science because it's a really possibility

    I stopped reading after the "with circulating laser beams" part. Yes, he will make the machine, but the only time he will be traveling to is his miserable future with his laserbeam box as the climax of his life. A joke.

    The main problem with timetraveling is that though traveling backwords in time, you and all other "mass" or "objects" will stay in place. (right idiot you're tavelling though time, not though space). The universe merriely will "slow down" - The basic mistake of people is viewing (or imagining) time as a film . The viewer belives that by rewinding the film, you reach a previous frame of the fim. The problem is though that the film is thousands of pictures aligned, instread of one state changing picture. All mass&energy in the universe moves though time, it doesn't leave a "film" which you can rewind to.
    Which leads to the conclusion:
    1. Yes, timetravel is possible ("wohhooo!")
    2. no, it will not bring you back to a previous state of the universe.


    I haven't come to fight my word, but to find the truth.

    "Professor predicts time travel by the end of this century"

    I'd change that to "Professor is a complete and utter F*cking idiot".

    Any form of mass/energy affects the curvature of space-time through the stress-energy tensor. So yes, light being energy can affect the curvature. And it quite well known that time is affected by the gravitational potential.

    But all that is one hell of a long way from permitting closed time-like geodesics in space-time.

    This guy has yet to be funded for this experiment. He may be looking a long time before he finds that funding.

    But I am pretty sure that he can find another gullible reporter fairly quickly.

    Hi,

    I also think his approach was not worthwhile. But, you never know what it was good for. He still was seeking funding for his research, who knows.

    But, time travel in general will be possible once you'll get behind the reason why the inventor wants to let it become reality.

    What he's failed to explain is how the results of his experiment are to be distinguished from ordinary effects due to time dilation.

    good luck getting funding if you don't address an obvious question like that.

    Admittedly the article is not very clear, and probably was written by a reporter who has no idea what he is talking about, but if one can take the words of the article as describing the phenomena proposed, then it is distinguishable from special relativityand ordinary time dilation.

    The article talks about particles nearby being influenced by the space-time curvature created by the light beams and therefore exhibiting a longer life-time than normal, because they " flowed through a time loop into the future".

    What appears to me to be missing is the fundamental justification in terms of general relativity.

    I predict that funding from any responsible normal source will be a long time coming. But I would not be surprised if a rich nut provided funding. Hold the phone -- this guy has written a book and sold movie rights to Spike Lee. He may gain access to a rich nut.

    Professor Predicts Human Time Travel This Century
    Here's a thought....why work on it at all this century? Just wait until time travelers arrive from the future and get the necessary information to build a time machine from them. Let the future come to us, so to speak.

    I mean if you do the spadework then it means nothing if a TT machine is successfully launched. So why bother?

    It's a bit paradoxical in a way. Let's say the professor's words come true and the first person to use the machine travels back to the 20th century and contacts the younger professor and tells him how to build it. In fact, it's possible that the professor could go back and tell himself how.(nah!)

    Well, that's how the professor got the idea in the first place. It was from his future self.

    I don't see any paradox there. It's a closed loop of cause and effect. The only difficulty is that one has throw away the notion of "free will."

    exactly, I agree with time travel if and only if all events in the universe were preordained to occur, in which case we are paradox free as we are all doing exactly as we are supposed to do... Not an idea I like to get behind though...

    I suspect that if any type of time travel device is ever invented, that the resulting time travel will be restricted to the time period in which the machine exists. IOW, the furthest back in time that one could ever travel would the moment the machine was first turned on.
    This of course would mean that the first successful test of the machine would result in the inventor being trampled by all the people pouring out of it in order to meet the inventor of the first time machine.

    I said a bit paradoxical. What I meant was that it seems as if you don't necessarily need to work on time travel machinery in order for it manifest itself. But I suppose somebody will have to, I guess.

    here's a thought. his future self doesn't come visit the present person because he will never get funding. ha!

    Or maybe he hasn't fully commited to it yet.

    Or maybe it's impossible.

    I doubt we'll ever be able to go back. Maybe go forward through time slightly, but we're still so clueless about it.

    Not at all! It's really quite easy. You just need to experience rapid acceleration to near c speeds, hang around for a while, then rapid de-acceleration. That can mean either spaceship travel or just hanging out near a massive body for a while, then leaving.

    Okay, well not easy per se, but definitely doable.

    lol

    Men could go back and forth in time if they would set off from time travel was not done on the same planet. Not at first the least. It's an enhansion ? of a space ships drive somehow, I would say.

    We will have to focus on traveling to an other (same ) planet earth in an other galaxy. Since, I could never travel to my own future therefore I had left it the moment I set off. It's being difficult to say, however and still does take a lot of time to get there.

    I'm curious if he does think an other probable planet earth could be effected by his experiments.? Like it was in Sliders, if I got this series right.

    Should I send an email to ask him?

    What I was trying to say was... we'll never time travel the way we want. Never how it is in the movies, never how it is in the books.

    I doubt it. What we should try instead was getting used to the idea no one ever is going to release the Enterprises warp drive to space.

    Such was not done with today atomic reactors or engines of any sort. And it won't be like that.
