    Time is merely a measurement. It is not something that is capable to be moved through.
    You moves through a few seconds of time whilst typing that.

    Heres an idea. Maybe we can create a time machine, that can transport people, but it needs a recieving machine at the other end. This means you can't travel back unless there is a reciever at the other end. You could go anywhere between the creation of the machine and the end of humanity.

    or even beyond the end of humanity? if you leave a machine lying around somewhere in space for ever.

    Sure, but then that isn't the end of humanity as we could go through and restart the human race at a later date. Also, all technology from the future would be available througout the timeline, making that machine the last invention ever. Theres another paradox for you.

    If time travel were possible, would you be able to go back in time and kill your grandfather in order to prevent your own existence?
    An entertaining SF story, The Men who murdered Muhammed by Alfred Bester, has a similar paradox: a mad scientist tries to kill his wife by building a time machine and murdering her grandfather...
    The best time paradox story is Robert Heinlein's All you Zombies. I'll leave it to you to find out how it goes.
