This article presents a critical–propositional analysis of Damir Duvnjak’s work, The a₀ Scale: A Covariant Action Principle Unifying Galactic Dynamics and Cosmic Expansion (Zenodo, 2026), in confrontation with the Theory of Objectivity (1.0). The study examines the article’s attempt to derive the MOND critical acceleration scale from the relation , and to interpret the geometric normalization factor as a consequence of effective dimensional reduction in the deep low-acceleration regime. The analysis develops a systematic dialogue between the physical structure of Duvnjak’s proposal and the modal discipline of the Theory of Objectivity, especially its axiomatic framework, its cosmogonic theorem, its phenomenic elements, its Inductive Effects, and its cosmological Eras. Special attention is given to both points of compatibility and points of tension. On the one hand, the analyzed article is recognized for moving beyond a merely empirical treatment of the MOND scale, for linking local galactic dynamics to cosmological conditions, and for offering testable predictions. On the other hand, the study argues that the proposal does not yet reach the level of ontological necessity required by the Theory of Objectivity, since it does not deduce the origin of the universe, the genesis of gravity, or the modal necessity of its own dimensional-reduction framework. The article further proposes an Objectivist reinterpretation of Duvnjak’s model in terms of the structural dependence of the local upon the whole, reading the deep-MOND regime as a late manifestation of cosmological induction over galactic systems. In this framework, the transcendent element is considered as the knowledge or information produced in atomic relations and equivalent to atomic radiations. Thus, the analyzed proposal is situated not as a replacement for the cosmogonic architecture of the Theory of Objectivity, but as a relevant regional theory of late-regime galactic phenomenology in dialogue with it.
