"In the non-Relativistic version you just postulate some point particles, and a single universal quantum state (represented by a mathematical wavefunction) and two simple dynamical equations: the Schrödinger equation for the wavefunction and the so-called guidance equation for the particle motions. You could have guessed both equations easily, and you get out all of the iconic quantum behavior: two-slit interference effects, violations of Bell’s inequality, decoherence due to observation or more generally due to coupling to the environment in the right way, etc., etc. What’s not to like? The only sticking point is the Relativistic version, but there I hold a minority view and would happily violate fundamental Lorentz invariance, explaining observational Lorentz invariance by appeal to what is called quantum equilibrium. There is a lot you just can’t do in complete thermal equilibrium, such as extract useful work from heat and send signals. Something you can’t do in quantum equilibrium is experimentally access a preferred “frame of reference”. C’est la vie."
