Is it possible to travel time with real life?
So, if time travel was possible, would it be dangerous to alter things in the past?
The idea of altering the past creates a paradox, known as the grandfather paradox. It suggests that if you alter the past, you could erase your own existence in the present. But there are also theories of parallel universes, where each decision creates a new universe, so altering the past wouldn't affect your own universe.
