Science fiction (or sci-fi) is a broadly-defined genre that involves the speculative use of science and technology. Science fiction is often, but not always, set in a speculative future of the real world.

Science fiction encompasses a number of subgenres, such as:

  • Cyberpunk: A dystopian subgenre where the advancement of technology and the decline of society are juxtaposed.
  • Science-fantasy: A crossover between science fiction and fantasy, presenting worlds where magic and modern technology coexist.
  • Space opera: A subgenre that focuses on the drama of traveling outer space, much like a sci-fi take on the older nautical adventure genre.
  • Steampunk: A retrofuturistic subgenre that focuses on the speculative uses of steam age technology.
