    WHOA!

    I swear I came up with that theory about 5 years ago in the pub when discussing the idea for a book with an author friend of mine (I read a lot of Stephen Hawkins ok..).

    I`m really not kidding either. The concept of multiple universes allows time travel. If you screw up your own timeline it just becomes an alternate reality. He even wrote a short story that was published about it.

    Way to go me..That made my day!

    Don`t believe everything he`s saying just because an old guy with crazy hair. Look at other sources for more info about time travel. I`m pretty sure there is no proof of multiple dimensions or forks in time. This is all theory. Also time travel to the future is much more likely than to the past. Traveling at light speed would disrupt time for the travelers. Invisibility might be the closest thing to fact this guy has mentioned. There could be suits that make the wearer almost entirely invisible in the future like he said. Look it up, people!

    No proof of forks in time? Absolutely not I suppose but it makes sense, imo. If I go back in time and kill someone there will be a new timeline started where that person is dead, and life is going without him. However who`s to stay my timeline has changed or has ceased to exist? If I went back in time and started a new timeline I should be able to go back to my own with nothing unchanged.

    Oddly enough, I`ve thought about this before (with the alternate timeline theory), though not nearly as in-depth. If he`s right, then we could be in an alternate timeline right now that branched off from the original. Weird.

    From what he`s saying: every time you time travel, you create (or go to) an entirely new universe (like Sliders). Lrom what he`s saying, there are virtually infinite number of universes already, unfortunately most of which, I assume wouldn`t have life on earth or even have earth.
    All this sounds a lot like sci-fi. However, there is research done on sending a molecule back in time. And they would only be able send the molecule to the time after the time machine was activated - very primitive, but at least it`s real.
    Time travel is still a popular fiction, just like robots were in the last century.

    @ PC-Player - Not necessarily. From what he`s saying, there could possibly be a virtually infinite number of universes. However, that`s only if time travel ever develops at all. Plus, even if it does, those who invent it might only use it once for some unforeseen reason, only creating one alternate timeline. In that alternate timeline, time travel might not even develop. Thus only two timelines would exist (assuming either that aliens don`t exist or humans are the only creatures with time travel).

    Whoa, Doc, this is heavy.

    lol Mjustin :p I`m an art major though so I`ll never take his classes. But I think he`s the same guy that teaches the really popular astronomy class too.

    After watching the video - hm. Going along with it for a second, how then do we know that this is the original universe, not a parallel? Maybe Wilkesbooth was a time-traveler and Lincoln wasn`t supposed to die...
    It`s a disturbing thought. And it reminds me of Stephen King`s "The Dark Tower" series, with all those different realities and worlds and stuff.

    The `Forking in the river of time.` was toootally dirty, but disregarding that, this made a lot of sense to me, just like the `Earth is Growing` theory that was posted a while back on here: Earth Science
    But in any case, were it true that we were a branch off of an original timeline, there would be no way to prove it, as we wouldn`t know the trigger that forced the change, and even if we did, changing it might just create a branch off of our own, rather than returning to the original.

    This just satisfied my geekdom. All previous literature on Physics told me time travel was not possible with the structure of our universe... but now, in theory, it can happen based off the new interpretation of quantum theory.

    I freakin` love time travel, and if I were actually any good at applying physics (because I`m not) I would be at work right now, building a time machine.

    Nerds can sum that in up a few simple words:
    Zelda Split Timeline Theory. You go back in time, but it ends up making an alternate reality in which two universe separately exist and function.


    The multiverse theory is possible. It`s also possible that this is the only universe, and time doesn`t even exist. Human life may never even have the knowledge to know the real answers, so we are based to believe or disbelieve theories. This one seems pretty decent, and can get rid of all those fears of time paradoxes, and sounds legit to begin with.

    there`s actually a theory that`s been around for awhile that`s quite close to this one. It says that every thing you do individually continues your universe but the other choices you could have but didn`t make spawn alternate universes. Where the equivalent of yourself lives with the consequences of the choices you didn`t make in this universe.

    No one is to say that there can`t be unlimited universes. So in an alternate universe I never posted this, and instead I`m on another webpage. Or perhaps in that universe I-am-bored was never created. Maybe they don`t have the internet. You just never know.

    As a physicist I disagree with quantum theory. I also disagree that time travel is possible. I do believe that there could be a multiverse, however..
    Because I`m actually procrastinating from studying for a quantum final, I don`t feel like getting into it, but I`ll basically state that I DO believe there`s something else to quantum theory that we simply haven`t picked up on yet.
    For example: the spectrum of hydrogen was known for quite some time, but people couldn`t explain why it happened that way.
    Here comes quantum mechanics! It explains the spectrum perfectly. But we don`t know why quantum mechanics works the way it does.
    Here comes ! It explains QM perfectly.
    The second part is what I believe will eventually happen..

    Ok "going back in time" ok fine, so you go back in time people find out that we can travel back in time, then the dude who actually invented it won`t even bother making it since it has been done, which would therefore lead to a paradox, how could those people go back in time if the one who made itpossible, didn`t make it? hehe, if it was possible we could see it today, right ? right ?

    I thought the same thing.

    Anyway, I think I get it.
    If you go back in time and somehow don`t change anything, then when you go back to the future (lol) everything will be the same and you`ll be in the same universe. But if you go back in time and change something and go to the future, you`ll be in a parallel universe...right?

    Eh.. this is a "weak" theory not a "strong" theory like gravity for example. It is not universally accepted by physicists. It is also very very difficult to falsify which puts it dangerously close to religion. It is extremely cool to think about tho and makes for awesome SF movies.

    This reminds me of an article I read on wikipedia regarding parallel universes and it states that if there are many universes in the world, then you will theoreticaaly "never die" because in different universes, different things are happening at the same time and so in some you will just keep on living and I think it said you may even switch over to another universe if you are about to die in the one you are in at the moment to prevent you from "dying" and this will continueso that "you" are dead in many different universes but the real YOU are still alive--or something like that...

    I read the book that they are talking about. In it, Kaku classifies "impossibilities" by how impossible they really are. He talks about time travel, invisibility, psychokinesis, mind-reading, and faster than light travel. His arguments for faster than light travel is similar to his argument for time-travel. If you could generate enough energy to bend space around you, then you could forego the cosmic speed limit because it`s allowed by the constraints of uncertainty. Yes, I`m going to be a physics major.

    "Time travel will never be possible.
    If it was, we`d be seeing people from the future, now"

    Time travel doesn`t work that way. One can only go as far back into the past as when the machine was first turned on. So if it`s turned on the date of May 1st, 2020 - humans can only go back to that date...

    Ronald Mallet, physicist, is currently working on building a time machine via Einstein`s theories.

    As for anyone who thinks that time travel is impossible because we`d have future people here now, 3 points:

    1) People from the future may be already here for what purpose, and nobody knows but them and future people.

    2) It may be absolutely impossible to travel back in time, only to the future.

    3) Future people may simply just be not interested in our present.

    The stuff he talks about is very basic. He fails to incorporate any solution to how to time travel other than the very basic structure of the general hypothesis`s (plural?) ontime.

    Basically, he says you would need to fold dimensions together to jump back and forth. He fails because there are COUNTLESS faults with this theory. I cant even be bothered explaining this all again, because every time we have a post of dimensionl hypothesis, or time travel, I always say exactly the same things, and go through every fault the theories have.

    In any case, I will give one. There can`t be anybody from the future who has traveled back to now purposly, because to travel back in time you need a sender, and a receiver. And no receiver has been built yet (NO! Black holes are not really ANYTHING to do with times o are NOT receivers)You need a receiver, because spontaniously appearing in any spot would essentially FORCE room for your body to come into existance, by pushing other particles away, con

    this would essentially have similar effects to several nukes hitting the exact instantaniously, wiping out a large area.
    To be honest, I think we would notice.

    There is no real way around this problem, because it still would cause minute explosions to introduce a body atom by atom, and it would cost insane ammounts of energy to do. and would take far to much time.

    Any questions 8)

    BirkirHe. The problem with forks is that we dont quite know how they work (assuming they exist). It causes a bit of a paradox in my head, because there are infinite possibilities, which is still increasing by an infinite ammount.. to be that equation is (infinite)^(infinite), which just seems insane.. then again, if there wasn`t infinite forks, which is a generally accepted theory, then there would be a specific number, meaning that we would have to understand what was happening in one of them perfectly to jump to it.. we can`t exactly use satnav to get there now, can we?

    I think time travel will someday be possible in a way and that time travelers have been here. this could explain the complexity of pyramids and other ancient stuff we dont understand. You might think, there should be more visits from people of the future. I can explain why this isn`t so. At the time someone invents time travel and he travels once, this will create a paralel universe because he is changing that reality even if he doesn`t do much (butterfly effect), and that reality will then be that much different so time travel in that reality will be invented at another time or not at all. That way you won`t get any more visits from the first reality. And in the end you are stuck in a reality in which time travel will never be invented. Just a theory..

    I don`t know if time travel is possible. It seems really really unlikely to me right now. However 200 years ago jetliners and missions to mars probably seemed just as unlikely. Of course so did a lot of other things that have since turned out to be impossible, like turning lead into gold. So I never say things are impossible, just very very unlikely.

    Mind experiments like this are useful tho, that is how Einstein figured out the whole relativity thing.

    but what if someone were to watch you go back? say you go back five minutes, move something, and come back. they`d still remember seeing you right? well what if you went back five minutes, sent them away, then came back. they wouldn`t remember seeing you, thus you don`t really return to the same alternate timeline.

    as einstein said though, you cannot just speak of time or just speak of space...time and space are a single unit, 2 bars of 2 different metals fused into one bar. but think about this, if you went back in time and saw your mother and she falls in love with you and you werent born, then you werent alive to go back in time and make ur mom fall in love with you, thus you werent around to kill your future self, thus you did not go back in time and are still alive. wrap your head around that.

    ridiculous. it places importanceon certain events causing a "fork" but ANY even would cause continual multiple forks! if u step on the grass in the past and kill a bug the knock on effects could be huge...each thing you do in the past will create too many outcomes.

    plus...

    you cant go back and change the future as the future depends on the past as much as the past depends on the future. so if you were to go back in time...you were always going to...and this would affect the future in the way it turned out.

    THERE IS ONLY ONE WAY THAT LIFE CAN GO AND ITS THE WAY IT HAS/IS GOING....i think lol

    People keep throwing the same question around. If time travel is possible, why hasn`t anyone come back in time yet? Well if you watched the video you should be able to work it out. Firstly, he says it would require the energy of a star. It`s not the sort of thing that you can just do on a daily basis. More of a one off "we did it!" thing. And why would any time traveller come to our crappy time if they could?

    And secondly, there`s no advantage to time travel because it affects other timelines and not your own (except one person, time machine and decades of work have gone). So why would anyone bother? Especially if there`s no way to guide a time machine or bring it back effectively. And this receiver business sounds interesting - giving a limited amount of places to go to. So really, this whole time travel lark is rubbish.

    E=mc^2 is the equation for nuclear energy, the difference in atomic wheigt when a radioactive atom emits radiation. Does anyone else know about Planck`s mathematics on timetravel, when Einstien said time travel could be done if we could reach the speed of light, Planck worked alongside him and concluded that it was impossible as the speed tended to lightspeed the mass of the subject would tend to zero, thus we could never actually reach the speed of light

    also i think that theoretical physics is really trying to be overcomplicated, coming up with fantastic equations to try and explain the universe, i bet it is a lot simpler than all of this. For instance when they came up for the orbital theory in the solar system, people said that the orbits had to be perfect circles because the universe is perfect.
    But the time frame didn`t work so they added smaller orbits of the main orbits and reversed the spin of the planets, coming up with all these crazy ideas that fitted this one idea to all the information, then someone came along and said the orbits were simply elyptical and lo and behold everything fitted.

    I think it`s impossible. The past does not exist. The idea of time as a line is not realistic- time is only the current moment. The past exists only in our memory, and the future exists only in our imagination. The only thing that actually IS, is the present moment. Also, it is impossible for one person to exist in two times simultaneously. Sure our minds can make it `theoretically` possible, but in REAL reality it simply couldn`t happen- and if it did, it would create MAJOR problems that we can`t even imagine. Also, if it does happen, why don`t we meet anyone fromt the future? Oh yeah, they`re invisible. Come on, can you really take that seriously? People find God/religion unbelievable, but then believe there`s invisible people from the future all around us? That guy needs to go to a psych ward.
