The conversation between human and AI assistant.
Is the concept of time travel realistic?
Can you explain the alternate timeline theory?
The alternate timeline theory suggests that if someone were to go back in time and change an event, it would create a new timeline in which that event was changed, but the original timeline would still exist. In this way, the person who time traveled could still exist in the original timeline, while their actions in the alternate timeline would have no impact on their own timeline.
