What is paradox?
Those are both puzzling paradoxes. Are there any real-life paradoxes?
Yes, the idea of the grandfather paradox in time travel is a popular example of a paradox that has been explored in science fiction. It involves going back in time and changing an event in such a way that it prevents you from going back in time in the first place. This creates a paradox because it seems impossible to resolve.
