This article offers a critical–propositional examination of Ozan Altıntaş’s Emergent Temporal Flow from Signature Change and its Cosmological Implications in confrontation with the Theory of Objectivity (TO). The study analyzes the article’s central thesis that temporal flow emerges from a Euclidean–Lorentzian signature transition and evaluates its claims regarding the Hubble tension, the tension, stochastic gravitational waves, dark-sector implications, baryogenesis, and the hierarchy problem. The paper argues that Altıntaş’s proposal is intellectually creative and heuristically valuable, especially in rejecting the naive primitiveness of time and in attempting to connect deep geometric structure with testable cosmological consequences. At the same time, the article maintains that, under the modal discipline of the Theory of Objectivity, the model remains ontologically incomplete. In particular, it is argued that the proposal begins from an already structured geometric level, does not sufficiently ground boundary, relational observability, and prior composition, and does not explicitly incorporate the transcendent informational dimension required by the Seventh Absolute Truth of TO. The study develops a systematic confrontation between the analyzed article and the foundational bibliography of the Theory of Objectivity, its recent modal and testability-oriented developments, and a wider supporting dialogue with modern physics, cosmology, and philosophy of science. It further proposes that Altıntaş’s model may be reinterpreted, not as a complete cosmogony, but as a partial and suggestive mathematical description of an intermediate phenomenic phase of cosmic emergence. The article concludes that the most fruitful reading of the Fluid-Time Paradigm is not as a final theory of origin, but as a formal representation of a derived cosmological transition, capable of entering into disciplined dialogue with the modal ontology, cosmogonic theorem, phenomenic elements, Inductor Effects, and cosmological Eras of the Theory of Objectivity.
