The late science fiction writer Robert A. Heinlein, in his story “By His Bootstraps” explores some of the paradoxes of time travel, which, since there really isn’t such a thing at this moment, isn’t really a problem. Not yet, anyway. In the story a person writing an article about the impossibility of time travel is startled to find someone standing in his room with a time portal, arriving from the future.
