Fictional technologies are imaginative inventions or concepts that exist in literature, film, and other media but are not real. These technologies often serve as plot devices, enhancing storytelling by introducing advanced gadgets, machines, or systems that challenge our understanding of science. Examples include hoverboards from the movie Back to the Future and lightsabers from the Star Wars franchise. These technologies can reflect societal hopes or fears about the future, exploring themes like artificial intelligence, space travel, and virtual reality. They inspire real-world innovation by sparking curiosity and creativity, leading scientists and engineers to develop new technologies that may one day resemble those found in fiction.
