This article presents a critical–propositional analysis of Hugang Cui’s Spacetime Substantivalism 29: The Mechanism of Antimatter Disappearance and Matter Existence and Its Relation to Proton Stability —— On Poisson's Equation as the Common Founder of General Relativity and Quantum Mechanics, published on Zenodo with DOI: https://doi.org/10.5281/zenodo.20222968. The analysis examines Cui’s thesis that Poisson’s equation functions as a common physical matrix of General Relativity and Quantum Mechanics, while reinterpreting this proposal in light of the Theory of Objectivity. The article argues that Poisson’s equation, micro-curvature, and the concave–convex model proposed by Cui may have operational value for post-metric physics, but they do not replace the pre-metric modal origin proposed by the Theory of Objectivity. The study articulates Cui’s proposal with the Eternal Triad of the first three Absolute Truths of the Theory of Objectivity: Nothingness as a primitive and eternal mathematical essence, the aura or field of uniqueness of every element, and infinity as the non-element necessary for the logical definition of the universe. From this Eternal Triad, the Perfect Sphere is interpreted as the initial modal logical matrix, still without measurable logical size, in which the concave and the convex occur in perfect equilibrium. The article further develops the Theory of Objectivity’s interpretation of the end of the Antagonistic Era, marked by the break number and by the simultaneous emergence of embryonic time, embryonic space, and embryonic memory. It also discusses the transition to the Era of Logical Tracks, in which the primary hydrogen atom of a single sphere begins to be formed through the fusion of ten primary plasmatic filaments.
