The Science of Star Wars is a nonfiction popular science book written by former NASA astrophysicist Jeanne Cavelos first published on April 15, 1999, by St. Martin's Press. The book uses fictional characters, worlds, and technology from the Star Wars universe as starting points for discussion of factual concepts in cosmology, biology, and technology, and discusses in a "semi-serious" fashion the scientific probability of such fictional elements. "It takes the fantastic elements of the movies—like faster-than-light travel—and examines the current state of science to see if they're possible". Source: Wikipedia (en)
