Four-Dimensional Conical Cosmology: Complete Derivation

This paper takes the physically real Primordial Quality 1 as the unique starting point of the universe, completely abandoning the abstract symbolic 1 in traditional mathematics and the three-dimensional cognitive system. Through complete, non-skipping mathematical and geometric derivations, it establishes a four-dimensional framework, a bidirectional expansion–contraction mechanism, a spiral structure, a 45° steady‑state inclination, and an ice cream‑shaped double‑cone standard cosmic form. Three fundamental formulas are strictly defined and derived, and Bi’s Circular Platform is proposed as the universal measure. This work reconstructs the underlying foundation of higher mathematics and physics, marking the entry of human civilization into the four-dimensional cognitive era.
