A Relational and Zero‑Proper‑Time Framework for Quantum Phenomena

Quantum phenomena are traditionally described in terms of states evolving in spacetime, yet the zero--proper--time behavior of massless systems suggests a different architecture: one in which propagation is not fundamental. Motivated by this observation, we develop a relational framework in which physical processes are represented not as trajectories but as relations between contexts and outcomes. The central object is a relational amplitude function R : B X O -> C, organized as a fiber bundle whose R_b are selected by experimental contexts. Expressed in standard mathematical terms---probability theory, quantum amplitudes, and fiber--bundle structure---this relational architecture is precise and unambiguous. Interference, entanglement, and measurement emerge as geometric properties of slice selection rather than as dynamical evolution of a spacetime system. Interference arises when a slice contains multiple coherent contributions; entanglement arises from the non--factorization of the relational object; and measurement corresponds to a context update rather than a physical collapse. The geometry of zero proper time motivates a shift from a spacetime ontology to a relational one, yielding a unified, non--spatiotemporal account of quantum phenomena. The result is a structurally simple and conceptually coherent reformulation of quantum mechanics that dissolves long--standing paradoxes and clarifies the relational foundations from which spacetime events arise. This is version 1.0 of the manuscript.
