SUBSTANTIAL SPACETIME, PHOTONIC PROTOCOL, AND THE MODAL DISCIPLINE OF OBJECTIVITY: a critical–propositional analysis of Hugang Cui's Spacetime Substantivalism 25 in confrontation with the axioms, phenomenic elements, Inducer Effects, cosmogonic theorem, and cosmological Eras of the Theory of Objectivity

This article presents a critical–propositional analysis of Hugang Cui’s Spacetime Substantivalism 25: Constitutive Audit of Substantial Spacetime — The Grand Unification of Materials, Fields, Vacuums, and Forces Confirmed by Gravitational Wave Evidence and the Intrinsic Work-Protocol , published on Zenodo with DOI: https://doi.org/10.5281/zenodo.20123003.

The analysis places Cui’s thesis of a substantial electromagnetic spacetime, governed by the intrinsic work-protocol , in dialogue with the Theory of Objectivity. It examines possible convergences and tensions between Cui’s proposed unification of materials, fields, vacuums, and forces and the modal axioms of the Theory of Objectivity, especially the principles of Nothing as a primitive mathematical essence, the uniqueness-field of every element, boundary, relational observation, prior composition, and substance transcendent to the quantum.

The article also articulates Cui’s framework with the phenomenic elements, Inducer Effects, cosmogonic theorem, and cosmological Eras of the Theory of Objectivity. Special attention is given to the role of radiation, information, photon-mediated processes, substantial spacetime, and the proposed interpretation of as a phenomenic index of radiative-informational stability rather than as the ultimate foundation of reality.

The analysis concludes that Cui’s work offers a significant field of dialogue with the Theory of Objectivity, particularly through its critique of non-instantiable infinities, its emphasis on finite physical boundaries, its search for ontological unity, and its attempt to reconnect physics with a substantive account of reality. At the same time, the article identifies important tensions, especially regarding Cui’s reduction of matter to photon proxies and the need for deeper modal grounding.
