likes to make a big deal out of this term and throw technobabble
around to make it look clever in an attempt to make the audience confused and thus ready to buy whatever crap the writers come up with.
Basically, a time paradox occurs if you time travel
and change the past so that it erases the possibility of you going to the past in the first place. Which means that events will occur as if you never traveled to the past, undoing your changes so you will travel to the past again, and so on ad infinitum.
Some writers think that it can destroy the universe. Or unleash killer flying time monkeys. Well, we haven't invented time travel so we can't test these theories.
- So, if I travel to the past to kill my grandfather, I'll create a time paradox and will never been born?
- Worse than that - if you travel to the past to kill someone and succeed, then you will have no reason to travel to the past at all! And without you in the past, events will happen as they originally did before you interfered. Time will be caught in a loop!
- Oh no!
