The Correlational Essence of Dimensions in the URUT Framework: A Unified Cosmological Framework from Zero-Dimensional Singularity to Three-Dimensional Entities

Traditional dimensional theories in physics have long been trapped in the underlying shackles of container ontology: they treat dimensions as a priori existing background containers of spacetime, failing to explain the origin of dimensions and the uniqueness of three-dimensional space from first principles, nor can they self-consistently unify the dimensional essence of singularities, matter, and interfaces. Based on the correlational ontology foundation of the Universe Recursive Unified Theory (URUT), with the core paradigm that “correlation precedes entity, and dimension is the metric of correlation rather than an a priori container“, this paper constructs a unified dimensional framework covering from zero-dimensional singularity to three-dimensional entities, from microscopic events to the full-cycle evolution of the universe.
