The Ontological Parallax of Cosmic Metrical Expansion — A Philosophical Deconstruction of Dark Energy

This study provides an epistemological evaluation of the foundational assumptions underlying the orthodox standard model of cosmology (), specifically examining the conceptual formulations of "metric spatial expansion" and "dark energy." We propose that the observed cosmological redshift may be interpreted not as an ontological stretching of the spatial fabric itself, but as an Observational Parallax arising from the structural limitations of localized empirical measurement frameworks. By establishing the concept of Cosmic-Velocity ( ) as an underlying meta-physical substrate, this paper reinterprets deep-space frequency shifts as an environmental state-transition of observations mediated through different metric densities. This alternative explanatory model offers a unified conceptual path to resolve contemporary cosmological challenges, such as the Hubble Tension and the Horizon Problem, without relying on additional physical variables.
