Aloha – Two great film series, Star Trek and Star Wars provide a fireworks display to demonstrate when a ship transitions to hyper-speed, or speeds faster than the speed of light. It turns out that the fireworks display will look more like a dull light.
Now keep in mind, if and when we do get hyperdrives we probably won’t have a lot of windows or balconies from which to observe the light show. Let’s enjoy the idea of interstellar space without concern about the initial blast of fireworks :o)
Meanwhile for the movie industry we need the fireworks for the dramatic impact, so George and JJ you can keep those fireworks coming :o)
