What technology or science from sci fi could not appear in Star Wars?

The total perspective vortex from hitchhikers.
I think it couldnt exist in the star wars universe because it's based on the hero archetype, which is inherently myopic.

Thanks for the post. I also want to know this and I am glad I have found your post. I was searching for the barber shops business plans online and while searching for the post, I have found your post.

Question to opening poster

Are you asking for things that cannot appear in star wars because of copyright or because they don't have that level of tech?

I used to wonder why the Empire’s ships were called TIE Fighters when no one wore ties. Found out much later tie was an acronym for Twin Ion Engine.

I still wonder how they’d know what a falcon is, though.

OT i heard the rules for a the first edition of Star Wars: The Roleplaying Game pointed out that “there is no paper in the Star Wars universe”.
