Physics and Star Wars
The space opera interstellar epic Star Wars uses science and technology in its settings and storylines, although its main focus is not necessarily on science. The series has showcased many technological concepts, both in the movies and in the Expanded Universe of novels and comics. The Star Wars movies primary aim is to deliver drama, philosophy, political science and less on scientific knowledge. Many of the on-screen technologies created or borrowed for the Star Wars universe were used mainly as plot devices or as aesthetic elements, and not as elements of the story in their own right.The iconic status that Star Wars has gained in popular culture allows it to be used as an accessible introduction to real scientific concepts. Many of the features or technologies used in the Star Wars universe are not yet considered possible. However their concepts are still probable.
