Sci-fi literature, or science fiction, explores imaginative concepts often based on advanced science and technology. It delves into themes such as space exploration, time travel, and extraterrestrial life, inviting readers to ponder the future and the possibilities of the universe. Notable works include classics like Isaac Asimov's 'Foundation' and Philip K. Dick's 'Do Androids Dream of Electric Sheep?'. This genre not only entertains but also provokes thought about societal issues, ethics, and the human condition. Through its unique narratives, sci-fi literature challenges our understanding of reality and encourages us to envision what lies ahead in our ever-evolving world.
