Science Fiction

Science Fiction (often shortened to sci-fi) is a genre of fiction defined by setting details such as imagined futuristic science and technology. They are often set on other planets, in space, or on futuristic Earth. Futuristic can mean 20 years in the future, 200 years, or even 20,000 years. They can also be set in the modern day, but with history changed by some event (e.g. human's brains did not develop the idea of war or religion).
