The Post-Realization Collapse of the Wave Function and Global Relational States: Determinism, Decoherence, and the Block Universe

Standard interpretations of quantum mechanics often maintain that physical reality is incomplete until it is observed, or else that the collapse of the wave function constitutes a fundamental ontological event associated with the act of measurement. Such readings conflate observation with physical interaction and reify the theory’s formalism into a metaphysics of indeterminacy. This paper proposes a reinterpretation of the collapse of the wave function as an effective, post-realization phenomenon: a descriptive projection that occurs within a globally relational state that is ontologically determined. By integrating decoherence theory, an analysis of the double-slit experiment, and a reinforced block-universe model, it is argued that quantum entities do not alternate between wave-like and corpuscular natures. Rather, different experimental regimes restrict the degrees of freedom accessible to local description, yielding distinct empirical manifestations. This approach preserves determinism, avoids an observer-dependent ontology, and provides a non-mystical explanation of quantum entanglement grounded in the ontological primacy of global relational structure over local spatiotemporal description.
