If one does go back in time and say for instance. Breaks up his mother and father or kills a distant relative thus providing that ones own parents do not bear an offspring. Then will one continue to exist or not? Will you exist only in the time you traveled to, or disappear when you return to your own time? Or is it whatever plain of existance that you are on?

Food for thought.

I think what oblio said in his last post can be applied here...if you read that article I linked to you will see how time travel would work....it eliminates possible paradoxes
