Predestination paradox / causal loop: The timeline is fixed and anything that happens due to time travel interference has always happened. A man goes back in time and accidentally introduces his parents resulting in his birth. Nothing changed.
Multiverse: Any interference / paradoxes that arise from time travel result in an infinite number of universes created. A man goes back in time and results in his parents never meeting. He is never born but continues to live out his life in this new timeline.
Timeline protection: There is only one timeline and all / major events are fixed. The Universe will interfere and stop any changes from happening. A man goes back in time and tries to keep his parents from meeting. Through a series of shenanigans they wind up meeting regardless and he is conceived and born as expected.
Rewriting history: There is only one timeline but it is changeable. But watch out. A man goes back in time and prevents his parents from meeting. Because he is never born, he vanishes from existence.
Interpret the question however you like, whether it’s how you prefer media to interpret it or how you think it would actually work!
