Science fiction is a genre of speculative fiction that deals with imaginative, futuristic and scientific concepts. These concepts may include information technology and robotics, biological manipulations, space exploration, time travel, parallel universes, and extraterrestrial life. The genre often explores human responses to the consequences of projected or imagined scientific advances.
Science fiction is related to fantasy, horror, and superhero fiction, and it contains many subgenres. The genre's precise definition has long been disputed among authors, critics, scholars, and readers. Major subgenres include hard science fiction, which emphasizes scientific accuracy, and soft science fiction, which focuses on social sciences. Other notable subgenres are cyberpunk, which explores the interface between technology and society, climate fiction, which addresses environmental issues, and space opera, which emphasizes pure adventure in a universe in which space travel is common.
