There is one other interpretation of Pilot Wave theory that is sort of the "inverse" of Pilot Wave. and to me makes more sense. The PW may be correct but the particles are not following a wave that is moving around them. What is happening is that each particle is 'emitting' (spherically and radially outward from itself) a wave of its own. It is the interaction of all other waves that cause the particle to move. Just like a particle with mass distorts the spacetime around it, in a 'static way', perhaps charged particles distort spacetime in a way that is directly tied to the speed of light, and thus distort spacetime in a 'dynamic way'. But the fact that the slit experiment "works" even when we know only a single particle at a time is being sent thru, it just makes more intuitive sense that the particle is neither interacting with itself, nor with other universes (copies of itself). So what i'm saying is PW theory is FAR more intuitive than Copenhagen many-worlds to me. I believe there is genuinely one particle going thru the slit experiment when we think there is, and it follows the path thru in a way that is statistically determines much more by a PW-type theory than any other theory.
