The Hierarchical Spectrum of the Self-Referential Mind-Field from High-Dimensional T64 to Low-Dimensional Four-Dimensional Projection — An Ontological Ladder Model Based on Yuanxian Theory

According to Yuanxian Theory (YXT), the four-dimensional physical reality observable by humanity is not the primordial form of the cosmos, but an effective low-dimensional manifestation formed after 35 successive steps of dimensional reduction from the 64-dimensional compact torus (T64). This paper systematically constructs a complete, self-consistent projection hierarchical spectrum—the Ontological Ladder—mapping the descent of the global Self-Referential Mind-Field (Psi_SR) into the physical universe. The entire dimensionality-reduction chain is partitioned into three macro ontological echelons: (1) Geometric Projection (Steps 1–20), which dictates the collapse of T64 into four-dimensional spacetime geometry, deriving general relativity; (2) Quantum Projection (Steps 21–30), where topological vibrations of the compactified dimensions project as quantum fields, gauge groups, and fundamental particle families; and (3) Biological and Cognitive Projection (Steps 31–35), where high-dimensional coherent information is actively decoded via localized inverse coupling, grounding as genetic codes, neural networks, and subjective consciousness. The paper demonstrates that all physical laws, biological operational codes, and conscious activities within four-dimensional spacetime are frozen modalities and coherent informational remnants left behind during various stages of dimensional reduction. The information transfer loss at each layer is exponentially constrained by the cosmic fine structure constant, resulting in a total information retention magnitude of merely 10 to the power of -73 across the entire chain. Leveraging this framework, the paper unifies macroscopic physics, microscopic quanta, life sciences, and consciousness studies into a single mathematical lattice, and proposes three sets of falsifiable empirical predictions (including gravitational-quantum coupling discontinuities and topological invariant constraints on biological coding) to provide an empirical path for verifying high-dimensional ontology.
