One thing I alaways liked about the old Star Trek was at some point Captain Kirk alaways needed more power from the engines. Scotty would tell him the dilithium crystels were deterorating and the ship was going to break up. One time the engines got shut off and Kirk told Scotty just to turn em back on and Scotty says "I canna change the laws of physics- I got ta have 30 minutes" We used to laugh so hard.
