Not to be that guy, but wouldn’t Star Wars be the “soft” sci-fi in contrast to the “hard” science-fiction of Star Trek?
Both are soft. Once you look past the technobabble, Star Trek has almost no scientific accuracy. Hard sci-fi, at least in my definition, is stuff that has at least the scientific accuracy of the movie Interstellar. That movie is the bar that separates “hard” from “soft” for me.
