Gerard 't Hooft [Physics] has an interesting idea that Quantum Mechanics is due to variables that move very fast. Not hidden variables. Nor any pilot wave. And in his theory space time itself is quantized. So how do you get from here to there? Maybe by worm holes? I mean to say that the connections between space might be worm holes. [This worm holes that connect between black holes in the core of atomic particles  I think was suggested by Robert Penna in NY [I should mention that I saw this idea of Robert Penna in a paper by Salwa Alsaleh whose papers I was reading.]
