The Spore Drive using a macro-sized water bear as a navigator is an ingenious sci-fi concept that's mostly unique and original. So sorry that some here don't see it. 'Stupid idea', they say. Same people that probably said in 1980: 'The greatest Jedi master is a green little goblin.. stupid idea!'
Star Wars is a fantasy movie, they can make whatever they want. I don't expect Star Wars to draw inspiration from theoretical physics.
