Is the concept of time travel realistic?
What about the Grandfather Paradox? If someone were to go back in time and kill their grandfather, how could they exist in the present to do so?
The Grandfather Paradox is a common argument against the possibility of time travel. It suggests that if time travel were possible, there could be situations where past events are changed, creating a paradox of cause and effect. However, some theories propose that the alternate timeline theory could solve this paradox.
