On the Integrated Ontology and Dynamics of Relativistic Quantum Mechanics, Relational Gravity and Cosmology

Foundational tensions between special relativity and quantum mechanics, together with conflicts between general relativity and quantum gravity, and unresolved cosmogonical and cosmological anomalies, block theoretical unification and limit explanatory depth. Based on ontological first principles rather than mathematical constructs, this analysis integrates a “discrete,” background-independent, relativistic 4D spacetime with a physically co-located Planck Domain. Through a one-to-one identity, the Planck Domain mirrors the discrete spatial elements of 4D spacetime, enabling a single, unified set of physical laws across quantum and classical regimes. Under this framework, ontic single- and N-body quantum states evolve deterministically in 4D spacetime and collapse instantaneously in the Planck Domain. Current theoretical tensions between special relativity and quantum mechanics, including nonlocality, separability, time, simultaneity, total energy scaling, and probability conservation, are reappraised by replacing the Hilbert-space wavefunction with an ontic energy field and a single energy-based operator that governs both motion and gravitational response. The identical ontological framework and dynamical laws apply unchanged across general relativity and quantum gravity, recasting gravity as the relational dynamics of discrete energy rather than the coupling of the stress-energy and metric tensors and reappraising the equivalence principle and the black hole information paradox. Cosmogonically, the same model re-examines the origin of 4D spacetime, accounting for near-homogeneity, isotropy, and low gravitational entropy without ad hoc assumptions, fine-tuning, or perturbative techniques, and provides ontological foundations for the cosmological constant and global energy conservation. Eight descriptive mathematical validations, derived from a unified evolution law, Planck Domain collapse rule, and the relational gravity law, support (but do not govern) the analysis: (i) the low-ℓ CMB TT shape generated from a field with one global amplitude on power; (ii) CHSH correlations at Tsirelson’s bound from collapse; and (iii–viii) hard-mass relational dynamics, highlighted by a tilted Earth–Moon orbit, a tilted hierarchical three-body system, and a high-energy Mercury–Sun analog, all sustained for 1000 orbits or inner orbits.
