Question

what is paradox grandfather

Answer 1

The grandfather paradox is a proposed paradox of time travel which results in an inconsistency through changing the past.

Answer 2

Grandfathers paradox is :-

There is a child ,his father and the child’s grandfather

The child got the ability to time travel

He time travels and kills his grandfather before he met his grandmother

So this is the conclusion of the paradox ,  SINCE HIS GRANDFATHER WASN’T THERE HIS FATHER WOULDN’T BE THERE WITHOUT HIS FATHER BEING THERE HE WOULDN’T BE THERE WITHOUT HE BEING THERE HE CAN NOT KILL HIS GRANDFATHER SO HIS GRAND FATHER IS ALIVE ………  SO HE IS ALIVE AND SO HE KILLS HIS GRANDFATHER ……………………………

this is a loop and this is the grandfathers paradox
