    Hi madanthonywayne,
    CANGAS is pulling your leg. There is no problem with this thread.
    I'm not sure what rules he's thinking of, but there is certainly no rule here that says a thread goes to Pseudoscience when it refers to a subject that cannot be proved.

    CANGAS,
    if you have a complaint with moderation, make a thread in Site Feedback where I can't edit it.

    Hehe, I just love some of these time travel gedankins. What would happen if the time traveller bumped into himself when he came back to his earlier location? They've got the answer! Same site:

    Although Time Travel has not been proven possible, it's still theorised and discussed in regards to Quantum Theory and Relativity Theory, this is because there are subcomponents of atomic states that do very strange things and the only way to try and express them is through theorising metaphysically since you can't think like a subcomponent you sometimes have to create elaborate stories to pose in essence what they get up to. It's also considered in regards to the future of computing especially within Parallel Processing Networking or Neural Networking since some nodes solution methods can involve gaining answers prior to other nodes of the same network and it generates the 'Paradox' usually associated with Time Travel theory.

    This is the reason that not all Time Travel posts should be moved to Pseudoscience Unless you claim your from the future (John Titter) and have travelled into the past to right some wrongs then you'll likely find your way there.

    I love that you bring this up! I tried explaining it to my dad, while watching Tim Cop (who has zero interest in the menutia of time travel) that NOT ONLY would it be infinitely impossible to travel back in time and determine the right moment, but there are also those exponentially complex equations that have to be involved in finding the right three dimentional location in space-time.

    the time space continium, ah yes i forget we live in the star trek universe

    , i know its a fun idea to toy with, but honestly time travel is pure fiction.

    this is no different that the god idea, we have no proof of it. there is no shred of evidence for us to observe, so why would i believe it to be true?. if i were to believe in something such as time travel, i might aswell just turn to the good book and be a catholic.

    no observation, no evidence, no fact, no proof, nothing atall apart from an idea spawned from imagination without any type of scientific basis to call on to back it up.

    but ofcourse in this universe it might be possible. but as for believing in it? i wouldent do that without evidence. so time travel goes in the pile with god, psycic powers, astrology and the rest of it.


    peace.

    I suppose you could only travel back in increments of one year to ensure the Earth was in the same place.

    yeah the problem is the placement of the earth

    , not the fact that you could go back in time and actualy meet yourself. basicaly turning the world of physics upside down.

    how on earth can you exist in more than 1 place at a time?, you guys might aswell just believe in a soul, astro projection, ESP, god, scientology, and everything else under the sun.

    Ps, why is this in the physics and math forum?, if i made a thread about ESP or some other weird and unproven subject wich is classed as woo woo central topic, then i would be debunked to the cesspool or worse the psudoscience forum. or rock bottom in the religion forum.


    peace.

    You mean like quantum superposition?

    if that is sci-fi then yes. what is the difference with believing in time travel and believing in god?


    peace.

    That's a pretty good movie. I like the scene where he appears right in front of a semi and must drop down immediately to avoid it.
    Our current understanding of physics makes time travel theoretically possible. Yes, it presents many paradoxes and may turn out to be impossible as a practical matter (while remaining theoretically possible).

    But is quantum mechanics any different? It doesn't make any damn sense at all! Electrons are not in any particular place, light is a wave and a partical, spooky action at a distance.
    I thought that at first too, but the whole galaxy is moving. So even if the earth was in the same place in it's orbit, it wouldn't be in the same place in space.

    I think this is pretty much the reason for the theory that if everything is kept the way it's suppose to be the equations are far simplified since they lack the Entropy caused by paradoxes.

    I'm one hundred percent certain that time travel is impossible, and is in truth crackpot pseudoscience. What's interesting is that when I explain why, my explanation is dismissed and ignored as crackpot pseudoscience. Once you understand time and some of the other basic concepts, you really start to notice just how much ridiculous material is being discussed earnestly and quite seriously, even by professional physicists - I'm thinking of the Boltzman Brains in my New Scientist a couple of weeks back.

    Pete is getting our goat ( get it, Pete? ) when he says that a thread that he claims is unprovable is not tossed. He has tossed more than a few on that unproven premise.

    As for the time travel thread, it has no time travel theory , no description of a time travel device, and its only redeeming feature seems to be reference to several science fiction episodes.

    Where is the SCIENCE in the thread? Or is the demand for science
    TOO MUCH TO ASK?

    CANGAS,
    Again, I ask you not to hijack this thread. If you have a complaint to make, make it in the appropriate place.

    Not one.
    You are a proven liar.

    And where is the proof?

    There are several different standard attempts to resolve or avoid the paradox. The most standard is to ignore it. By sending someone far enough into the past, we do not know what influence that person will have and thus for all we know the person caused the world as we know it today. Another way to avoid the paradox is to state up front that we cannot change the past. There are different versions of this thesis. One is that we can go back and participate in a past causal chain but only in the way that already happened and the other way is to go back merely as an observer.

    Another question we may ask within this view of one timeline being replaced by another is at what point does it happen. The standard view, which seems totally incoherent, is that it happens when the traveler makes the important change.
