    That's called a paradox. 

    Say you built a time machine. 
    Stepped in it.
    Went to the past, when you were walking into the machine itself.
    Shot yourself.
    Did you die?

    If you killed yourself, you didn't travel time.

    If you didn't travel time, you didn't kill yourself. 

     In so many stories, the traveler goes to a place in the past so as to change someevent that will alter the future. This was the job of the terminator inTerminator 1. His task was to kill the mother of his enemy before sheconceived. But now let us ask "what would this accomplish" Accordingto our model, the terminator, if successful, travels from c to b and kills hisenemies mother. The terminator then proceeds to lead a quiet little life ontime branch bef. But has he changed the place from whence he came? If we holdthat both timelines are equally existent then it seems that the entities thatsent the terminator at best only created an alternate universe where theirenemy doesn't exist. The original timeline will proceed as it would withoutchange except for the loss of one terminator who has left to occupy analternate time line. It is hard to imagine the motivation of these entities inthe future to create such branching events since from their viewpoint all theyhave accomplished is getting rid of a well trained killing machine that was ontheir side.


    Yeah by myself.

    Untrue. The timelines will split in dimensions- one where you time traveled but did not shoot yourself and one where you shot yourself, therefore you didn't travel in time. You are currently in the one where you did shoot yourself, so all you'll do is disappear from that specific dimension. The timelines cannot be reconnected, therefore, time will continue as if you shot yourself within your dimension.

    AAAAAAAAAAAAAAAAAAA! imageimageimage

    This is only as much of a solution, as is leaving your house front door open, so you don't need to lock the door!

    If Time Travel is possible, why haven't we broke it? Voyager 1 was one of the fastest man made objects built. If you don't get what i said, don't respond at all.
     
    Yet, the response will be "You have to travel faster than the speed of light in order to do that". What? What? We could just make a freaking Chronosphere and teleport ourselves back in time to kill Obama and stop USA's debt from expanding beyond the reaches of the universe.

    Forwards time travel is possible, but requires us to go about 99% of the speed of light, something we can only achieve with a few atoms at a time... Backwards time travel is impossible.

    No, not entirely. We've succeded in transporting some photons... I think it was 300 nanoseconds backwards?
    Not enough time for a shoot your parents paradox but more than enough time for a crash your computer program paradox.
    Why didn't they try that...

    Well, it's going to take atleast a few decades to send things back hours... let alone years... Forwards, not so much... We have already found a particle that can break the speed of light. If we can manipulate it enough, forwards time travel isn't so far fetched.

    Someone's been seeing way too much Michio Kaku on Discovery Channel. Anyway, how'd you get that transcript?

    With the terminator thing, it is really only advantageous for the terminator that gets sent back.
    o_O
    In addition, time slows down for any object with any speed, but only fractionally... therefore not enough to be observed.

    You don't belive in stuff that can't be proven? Are you religious?

    @m I belive this kind of thing, but only to a point. If someone travels, they are gone off to somewhere else where time slows down. They are not at Earth. When the come back, sure, years will have gone by.

    Through the wormhole, the scientist can see himself as he was one minute ago. But what if our scientist uses the wormhole to shoot his earlier self? He's now dead. So who fired the shot? It's a paradox. It just doesn't make sense.

    he doesnt see himself, he sees his copy in alternative reality, which was created when he opened the wormhole, so if he shoots his copy, he himself wouldnt be dead, he will be just in alternative reality, not the main one, which he came from.
