The Grandfather Paradox
I read the Grandfather Paradox link that buen posted and correct me if I'm wrong here, but I think I see a flaw. Assuming that there is only one time line, some time in the future someone travels back in time, then kills their grandfather. Ok. Now that person will never be born. However the single time line can surely remain, however now the time traveller never existed. Any takers?

He went forward in time to just before you had the time machine. He then killed you. You would not have gone back in time so he could steal the time machine....and so on and so on (continue for as long as you like).
