Science fiction is characterized as a genre of speculative fiction that explores imaginative, futuristic, and scientific concepts. These can encompass a wide range of themes, including advanced technologies like information technology and robotics, biological modifications, voyages into space, the concept of time travel, the existence of parallel universes, and encounters with extraterrestrial life. A common thread in science fiction is the examination of how humanity reacts to the potential outcomes of scientific advancements, whether real or imagined. The genre is closely related to other speculative fiction forms such as fantasy, horror, and superhero narratives, and it is further divided into numerous subgenres. The exact definition of science fiction has been a subject of ongoing debate among creators, critics, scholars, and readers.

Within the broad category of science fiction, several distinct subgenres have emerged. 'Hard science fiction' is noted for its emphasis on scientific accuracy and detail. In contrast, 'soft science fiction' tends to focus more on the social sciences and their implications. Other significant subgenres include 'cyberpunk,' which delves into the intersection of technology and societal structures, and 'climate fiction' (or cli-fi), which addresses environmental concerns. 'Space opera' is another notable subgenre, characterized by its focus on grand adventure within a universe where space travel is commonplace.
