The Ontology of the Many-Worlds Theory

Abstract

It is shown that the wavefunction describes our observations using the postulate that relates position to the distribution |Ψ|2. This finding implies that a primary ontology is unnecessary. However, what is real is not directly represented by the wavefunction but by the gauge invariants. In light of the presented ontology, Spacetime State Realism becomes not a fundamental ontology but derived.
