- A man travels back in time and kills his biological grandfather (on his mother's side) before his mother is born.
- As a result, the man's mother (and by extension the man himself) would never have been born.
- If the man was never born, he could not have travelled back in time after all, which means the grandfather would still be alive.
- This means the WOULD have been born, allowing him to travel back in time and kill his grandfather.
- Thus, each possibility seems to imply its own negation, a type of logical paradox.
a) Time travel is impossible
b) The human brain is not capable of the complexity needed to solve the paradox
