Thus, the ontology of pilot-wave theory contains as the trajectory formula_15 we know from classical mechanics, as the wavefunction formula_16 of quantum theory. So, at every moment of time there exists not only a wavefunction, but also a well-defined configuration of the whole universe (i.e., the system as defined by the boundary conditions used in solving the Schrödinger equation). The correspondence to our experiences is made by the identification of the configuration of our brain with some part of the configuration of the whole universe formula_15, as in classical mechanics.
