I've recently decided that in Star Wars, space is actually filled with some sort of medium -- let's call it Ether -- which would explain the sounds, the maneuvers of ships and fighters, the fiery explosions, and why in The Last Jedi ships don't have infinite momentum.I don't know from science. If they can have sound in space without air, move ships at the speed of plot and communicate vast differences until they can't...well, as long as it's not a boring story and they don't have people doing spacewalks without some kind of EVA wear, I'm good.
