    I think time travel is an impossible thing to do, and it will never be achieved in the future. Going back in time could cause big changes to the history and the future. Imagine if you would go back in time and kill your mother when she was young, and then you get back to the normal time. You would not exist.

    Possible, quantum physics says it is possible for atoms to exist in more then one place at a time, so it wouldn't be like "oh lets go back to the 50s" it would be going to a different space, there for time. Like the idea of a worm hole, taking gravity to shorten the fabric of space time between two points. Like holding a blanket at two ends, then butting a bowling ball in the middle, the two sides get closer.

    i think time is a direction, like up, down left or right. like length, depth, width.

    I personally believe that time is a local phenomena associated with mass and consequently, gravity.

    I don't believe that it's a dimension at all.

    I honestly don't think it's possible. I mean if there weren't any boundaries then something would have gone back in time and fucked the whole universe. I am a dumbass though so I have no knowledge or scientific evidence to back anything up, this shit is way over my head.
    Well, the 3 possible reasons why we have not seen ourselves from the future is A: It is illegal to do that in the future. B: You can't time travel. C: You can make a time machine, but it can never go back to a time before the time machine was created.

    I think the answer is C, because A would probably involve someone breaking the law, B looks easily wrong, and C has very good theories to back it up.

    The wormhole method of time travel allows the user to travel back to a certain date in time, but that date is never before the time machine was created, just like you can't travel through a tunnel that goes from the north pole to the south pole and end up in the tropics, unless during the time dilation part of the process, you can move one end of the wormhole faster than the speed of light.

    Edited:

    I can answer that also. When you travel back in time, a new universe is created and added to the unlimited store of universes, which is the the one you end up in, so when you kill your to-be mother, you are actually killing the potential mother of someone identical to you (Identical if you exclude the massive butterfly effect that would be caused by your teleporting into this universe). So you can never travel back in time to murder your OWN mother, even after she gives birth to you. You will always end up murdering somebody else's mother who is identical to yours.

    i dont know, thinking about time travel, you could assume that past, present and future are happening and that they are all here, somewhere.
    every millisecond would be one different reality, with lots of different possibilities.
    So if time travel is possible, so is multi universe existence.

    Somehow be in the orbit of a super massive blackhole, and boom you're gonna be in the future.


    Though time travel backwards is probably never going to happen.

    They could very well be. They could be merely staying quiet and low whilst watching a event. A traveller from the future will have knowledge of what happens next, so who knows.

    I want to think it's possible. They (Berkley College) recently discovered something that travels faster than light with may be a big breakthrough in the world of physics because it breaks every rule the natural world is built upon.

    I'm pretty sure we'd notice if time travel backwards was possible.


    Also, for time travel backwards, you'd somehow have to rearrange every atom as it were at that moment. Which is impossible.

    To me, time travel backwards is nothing more than fiction.

    While time travel to the future is still possible, I mean the guys up at the ISS are technically "time traveling" as we speak.

    I'd like to point out (sorry if I'm late) that if time travel is possible, then alternate realities probably are as well.

    The world cannot simply change in the blink of an eye, and really that wouldn't make sense anyways as it would already of happened. E.G. if I go back in time and stop the computer from being invented, then obviously none of your computers would suddenly disappear. However in my timeline, they'd of never existed.
    So any changes to the past would only affect the time traveler's own timeline. Each time he went into the past, he'd be creating a new alteration to his timeline.

    This could also very well explain the age old question of "If Time Travel is possible, where are all the Time Travelers?"

    You putting your foot on the ground would cause a gigantic very long chain reaction and it would change the "future".

    It's impossible to not "change" anything while in the past.

    In order to move through time, you would also need to move through space, lest you end up inside of a rock or in space.

    It's contradicting.. possibly fiction, not that it isn't science-fiction anyway.

    But some worm-hole type exploit in space sounds plausible. Either that, or we need a hell of a lot more speed if we ever want to explore space.

    Just to get an idea of what time is, time is actually bent by mass and gravity, for example space agencies had to run the clocks on satellites very slightly faster/slower (can't remember) as there was a slight time difference to standing on Earth, also the theory goes that around a black hole time would be a lot faster/slower (again can't remember but you get the point).

    Time travel backwards forms a paradox and therefore is not possible, imagine a man has a briefcase with a gun. He pulls the gun out of the briefcase and walks through a portal back in time (seconds before) and can see himself pulling the gun out of the briefcase. He shoots his 'future' self as his 'future' self pulls the gun out. Then if you think about it, how could he shoot himself if he never pulled the gun out in the first place? A paradox.

    Time travel forward is theoretically possible because as an object approaches the speed of light time will slow down so that the object never quite reaches it. This means that if you are travelling in a ship close to the speed of light you would be able to live a much longer life than a normal person but time would seem completely normal to you although everyone else would be going a lot slower. The same goes in the reverse, people on the outside would see you going a lot faster.

    I don't know.. I think all life in the universe is connected through time. Say, there is another civilization on the other side of the universe (like, very far away) and on the other side of the universe, there's us and our planet.

    So; When I light up a cigarette on our planet and smoke it for about 3 minutes, at the same time on the other side of the universe, some other creature somewhere far away does his activity, doesn't matter what activity. Being alive.

    Like, me a Finnish person, then an American person (the alien far away). We do things at the same time, like when I'm out of school, the American is sleeping. Only with two entire different galaxies, we do something, and they do something at the same time. Right?

    I remember hearing something about traveling back in time being impossible, but SEEING back in time being possible with some gigantic mirror out in space. The light from what is happening right now would take time to get to the mirror and additional time coming back, which you could then observe x seconds/minutes/etc later depending on the distance.

    the only problem with this is that filming something is a billion times easier than launching a gigantic friggen mirror into space and then figure out all the necessary garbage needed to observe it.

    And everyone who has ever read a little into Einstein's theory of relativity would accept the fact that time "traveling" forward is possible. I don't see it as traveling though; more of slowing down time for yourself whilst everyone else move at the constant "speed" of time.

    Even if time travel is possible, it would be currently possible but also wouldn't. For example people think things in the universe would change while in reality, no one would ever really know because it would be changed before they came into existence. And time is something humans made, up although it is just to measure how long humans have been in existence, and to measure people's lives, etc. Time travel wouldn't be possible because time is a man made thing.

    *Time as a measurement, not as life cycles, day and night or years, months, or days (which are subdivisions of time)

    Time isn't only used for measuring human lives. Thanks to time we can somewhat comprehend how old the universe is, how far away stars are and the age of those stars. Time isn't some magical thing that humans invented to give ourselves order in daily life, time is everywhere in the universe. In some places time acts differently. On Jupiter time would be different because of its huge mass and vice versa on lets say Pluto.

    Although it would be technically possible to travel to the past through a wormhole, the universe is interesting character in its own way.

    Listen to this
    The wormhole is a entity in space which would allow you to go back to the past with 2 connected ones. However, the universe to protect itself from paradoxes, and trust me it will sound extrememly crazy (and you don't even know half of it), would close the wormhole right before you are able to pass and accomplish any paradox. This is technically proven because or else we would have travelers from the future accomplishing paradoxes.

    Thats assuming paradoxes like your talking about are possible.

    One of my theories is that in small chance we do get to time travel, it would cause a split in the time line the instant we changed something, like if one were to travel backwards in time.

    Lets say I wanted to see myself roll over my go-kart from another angle other then underneath the damn thing, so long as I had no effect on the outcome and stayed out of sight history, as it were, would continue on till I left.

    But what if I wanted to keep myself from this event? So I (future me) stab a hole in all the tires keeping this from ever happening, instead of changing the future I exist in, it would in theory cause a split at the point of my intervention creating a new future. Yes, this is based off of BTTF but there's a reason this (can) make(s) sense. Time is a measurement, man made idea to keep track of things in history, but history is just that but also in that it happened. An alteration in history could in theory cause a duplicate universe paradox, the original time line going on as nothing happened and then the new split where a new event occurred.

    On the idea of meeting your self a couple of things could happen.
    1) You could cause a collapse in time space, because two of the same persons history probably can't exist in the same space.
    2) Your future self ceases to exist transferring all experiences to your past self and collapsing the split time line to become one again.
    3) Nothing happens and you both go play SMB or go to a bar telling the ladies your very late twins in a medical marvel and mystery.

    This is all still theory and I make no claim that any of this as fact, just speculation. Theres still way to many possibilitys for one person to come up with and until someone gets one right, we may never know.

    Or, someone gets there and gets the bright idea to see what it's like to do them self, making the universe basically divide by zero. Who knows....

    I think we will most likely get the ability to generate traversal wormholes than achieving time travel.
    I mean, we have teleported photons, and laser beams, it's only a, matter of time.

    It is also possible that we did achieve time travel and some future terrorist got it and rigged the 2000 elections.
    There's a lot of things that could have happen to affect us in this moment if, in the future time travel was achieved.

    Also, I don't if anyone saw the Family Guy episode last Sunday, but that is what could happen with time travel. Things happen for a reason, and it should stay that way.
