Addressing Higher-Order Partial Derivatives in Wave Equations of Quantum Field Theory in a Curved Spacetime

In considering a Relativistic Quantum Field Theory an unaddressed facet is the ontology of higher-order partial derivatives of wave equations should an eternalist spatiotemporal nature of the universe be proven accurate. This project offers a novel position by reinterpreting higher-order partial derivatives of relativistic quantum wave equations as useful for a putative delineation and indexing of a Relativistic Least Action Block Multiverse, where wave functions are better understood as depicting “possible” locations of a hypothetical particle, vs. the “probable” nature presumed in Copenhagen-aligned interpretations. In the proposed paradigm, putative ‘Orders of Reality’ and ‘Parallel Universes’ may be accounted for mathematically, while simultaneously considered in the context of relativistic tweaks to a Least Action Many Worlds Interpretation, which offers hints about the nature of energy throughout the multiverse. The analyzed equations address compatibility questions regarding Free Will, Determinism, Locality, Born’s Rule, The Measurement Problem, etc., with falsifiable tests offered for portions of the presented quantum mechanics interpretation (which is compatible with Quantum Field Theory in a Curved Spacetime): the Relativistic Least Action Block Multiverse.
