A few days ago I got wind of a rumor that the upcoming “Rogue One” Anthology film was going to be “more scientifically sound” than the other Star Wars films. Then to back it up, there comes the news story that screenwriter Chris Weitz actually tweeted physicist Neil deGrasse Tyson for some questions about astronomy.
Science is not what they should be worried about because Star Wars already blows holes in accepted scientific theory. Ships do not make noises in space or move around in high speeds in all directions nor are fiery explosions (that you can hear) possible. But that’s the tradeoff so the space scenes are not boring. As for planets and stars and suns, they should look cool. Period. That’s all you need to worry about.
Star Wars is space fantasy, a mythology that just happens to have sci-fi window dressing. It is not hard science fiction. While you can monkey with some things stylistically with these spinoff movies, making it “scientifically accurate” or trying to cram it into a hard sf box is fundamentally changing Star Wars’s DNA.
