In this episode an astronaut returns from a voyage to find the world not quite the same as he remembers it. It was an early example of the concept of mirror or alternate universes.<ref>{{Cite web |url = https://collider.com/the-twilight-zone-hard-sci-fi-episodes/ |title = The 15 Best Hard Sci-Fi Episodes of ''The Twilight Zone'' |date = April 3, 2024 |access-date = May 28, 2025 |first = Andrea |last = Ciriaco |website = [[collider.com]] }}</ref> The ''[[Star Trek: The Original Series]]'' episode "[[Mirror, Mirror (Star Trek: The Original Series)|Mirror, Mirror]]" was another example, although the differences between the characters in the two ''Star Trek'' alternate universes were quite noticeable. The concept has also been used by both [[DC Comics]] and [[Marvel Comics]] in their comic books and cinematic universes.
