This article is a sequel to a recently published article by the present author (IJQF, 9,4). That article seemed to go some way towards providing a physical explanation of the mysterious probability amplitude nature of quantum mechanics’ psi waves, and in that way towards a possible solution to the measurement problem of quantum mechanics. This article begins where the previous article finished. It puts forward a ‘local’, causally deterministic, additional variable model of a quantum system’s transformation from the potentiality described by the psi function into actuality. The model’s key element is the deeper-level, periodic physical process (double transition\basic process) postulated in the previous article. The model specifies what the additional variables are and how they work—and the sense in which they are ‘local’. It explains the ontology of the potentiality represented by the psi function in terms of the underlying double transition\basic process. The model is time-reversal invariant, and encompasses both fermionic and bosonic systems. Because the model is explicitly retrocausal—the possibility of retrocausality already latent in the basic process—it readily evades the various ‘no-go’ theorems, such as Bell’s theorem, usually taken to show the impossibility of a local hidden variable model that agrees with the predictions of quantum mechanics.
