GRAVITON, SUBSTANTIAL SPACETIME, AND THE MODAL DISCIPLINE OF OBJECTIVITY: a critical–propositional analysis of Hugang Cui's Spacetime Substantivalism 32 in confrontation with the axioms, phenomenic elements, Inducer Effects, cosmogonic theorem, and c

This article presents a critical–propositional analysis of Hugang Cui’s Spacetime Substantivalism 32: The Truth of the Graviton Confirmed by Gravitational Waves and the Grand Unification Reduction of Quantum Gravity — The Constitutive Audit, the Physical Restoration of Tesla's Dynamic Theory, and the Closure of Monistic Substantial Spacetime Dynamics (CSSD), published on Zenodo with DOI https://doi.org/10.5281/zenodo.20350378. The study examines Cui’s proposal of electromagnetic substantial spacetime, his ontological relocation of the graviton into the gravitational constant , and the Unified Constitutive Field Equation in confrontation with the axioms, phenomenic elements, Inducer Effects, cosmogonic theorem, and cosmological Eras of the Theory of Objectivity (TO). The analysis highlights strong points of dialogue between Cui’s CSSD framework and TO, especially regarding the search for a deeper ontological foundation for physics, the critique of fragmentation between gravity, electromagnetism, quantum theory, and relativity, and the interpretation of gravitational waves as objective signs of cosmic relational structure. At the same time, the article identifies important tensions. From the standpoint of TO, Cui’s electromagnetic matrix cannot replace Nothing as primitive and eternal mathematical essence; the transcendent element is not merely a physical substrate, but knowledge/information produced in atomic relations and equivalent to atomic radiations; and the rejection of the graviton as a discrete particle requires greater empirical and conceptual caution. The article concludes that Cui’s work offers a highly fertile phenomenic contribution to TO, provided that its constitutive claims are reorganized under the modal discipline of the Seven Absolute Truths.
