Science fiction (often shortened to sci-fi or SF) is a genre of speculative fiction which deals with imaginative and futuristic concepts such as advanced science and technology, space exploration, interstellar travel, parallel universes, and extraterrestrial life. It has been called the "literature of ideas", and it often explores the potential consequences of scientific, social, and technological innovations.[1] Science fiction stories can be novels, movies, TV shows, video games, comic books and other literature.
SF is often about the future. It can be about imaginary new science and inventions such as spaceships, aliens, and robots. Science fiction stories are often in a world that is very different from the real world. They can have science and tools that do not exist in reality. Science fiction stories often take place on other worlds. There are often alien creatures.
Science fiction is drastically different from fantasy. Fantasy stories often have magic and other things that do not exist and are not science. Isaac Asimov was a famous science fiction writer. He once said that science fiction is possible, but fantasy is not.[2]
Writers often use SF to explain everyday questions or problems by putting them in the future. Usually they invent a very different world to help people notice important ideas.
