In A New Hope, all of a sudden there was sound in space.
Not the first SF film to do that.
Fair, but it still contradicts real life. Therefore, star wars physics is not equal to real life physics.
FFS, I can’t believe this particular argument still gets used.
Most sci-fi (or science-fantasy/space opera/what the @##$ ever) has sound effects in space; even Alien — the movie with the famous “in space no one can hear you scream” tagline — has them. It’s not indicative of any in-universe phenomena; it’s artistic license, pure and simple.
