Can time travel exist somewhere in our universe already?
What about the grandfather paradox? If someone were to go back in time and accidentally prevent their own birth, how would that work?
The grandfather paradox proposes a logical inconsistency in the concept of time travel, as it would imply that changing the past could invalidate one's own existence. However, some physicists suggest that the universe could exist in multiple timelines, allowing for alternate versions of events to occur without interfering with the original timeline.
