Ontological Universal Entanglement Field Theory (OUEFT) — A Relational Ontology Deriving All Physics from Primordial Quantum Entanglement

Ontological Universal Entanglement Field Theory (OUEFT) is a unified relational ontology deriving all physics from a single primordial universal entanglement field Ψ_U, a timeless zero-entropy state realized as the full operator algebra of the celestial conformal field theory on null infinity. The Ψ_U balancing network undergoes spontaneous bifurcation via minimal soft-operator insertion into braided topological defects. Spacetime and gravity emerge entropically from swing-surface correlation gradients (Apolo et al. 2020), gauge forces arise via Chern-Simons actions on entanglement horizons, and conserved linking numbers explain non-locality mechanically via generalized wedge connectivity (Bousso & Penington 2023). An explicit flat-space toy model—type-II parametric down-conversion producing a polarization-entangled Bell pair—demonstrates the axioms in the laboratory, with the swing-surface bench length rigorously derived from Minkowski geodesics in Appendix A. The framework incorporates the celestial holographic dictionary as the precise flat-space realization of Ψ_U, with swing surfaces providing the canonical geometric definition of entanglement entropy and generalized wedge connectivity supplying the dynamical emergence principle. This ontology resolves longstanding puzzles—including quantum entanglement, Hubble tension, and the origin of structure—while remaining compatible with the Standard Model and general relativity. A new quantitative model of spatially and directionally variable effective cosmological constant Λ_eff (Section 5.3), calibrated to the observed pancake dark-matter sheet (Wempe et al. 2026), unifies all local-structure anomalies. A cluster of CP-violation and flavor measurements in the beauty sector (LHCb and Belle II 2025) provides quantitative calibration of the braid-CP coupling and confirms the primordial bifurcation mechanism that solves the full cosmic baryon asymmetry. The framework further reveals an eternal hierarchical structure: variable-Λ_eff-driven differential dilution in cosmic voids preferentially nucleates local near-perfect states that spontaneously re-bifurcate, spawning fresh emergent layers that grow within the dilute background of previous cycles — a relational fractal multiverse unified by the single timeless Ψ_U. The Law of Absolute Nothing functions as the eternal asymptotic regulator of this self-reproducing structure, driving perpetual relational emergence before exact global perfection is ever reached while preserving all topological invariants. Sharp, quantitatively falsifiable predictions are provided in quantum optics, cosmology, high-energy physics, baryon decay phenomenology, and directional CMB residual signatures.
