After recently binge watching Star Wars, Star Trek, and Battlestar Galactica as part of another attempt to put off Calc homework, I realized an error common to almost all space related moving pictures. During their frequent shots of large ships flying through space, the sound of the ships' engines can often be heard. However, because space is a vacuum, there can be no sound in space. Without air molecules to vibrate, how can the sound of the ship's engines be heard? While it does make those ubiquitous shots less boring, it is an oversight on the account of George Lucas and all the other film makers who tried to piggy-back off of his success.
