Ah- Sorry! [Words, how does he do them.] A 'temporal paradox' means basically... Well, I'll give an example.

If you take something to the past, and use it to create that something in the first place, then it creates what movies and books refer to as a 'time loop'. Since it was created in the past, it's no longer created in the future, but if it wasn't created in the future, it can't have been created in the past. That's a temporal paradox!
