Is it possible to time travel to past?
What about the grandfather paradox?
The grandfather paradox is a common time travel paradox where one goes back in time and kills their own grandfather before their parent is born. This creates a paradox because, if their parent was never born, then the time traveler could never have been born in the first place to go back in time and kill their grandfather. It's one of the many theoretical issues with time travel to the past.
