The Unified Conical Cosmos Model: Causal-Geometric Solutions to the Three Fundamental Problems of Microscopic Physics (V4.1 | Part 1)

This is Version 4.1 (Part 1) of the Unified Conical Cosmos Model series. As the foundational full paper of the upgraded theoretical system, it provides rigorous causal-geometric solutions to three fundamental problems in microscopic physics: the origin of the fine-structure constant α, the inertia–gravitation equivalence principle, and the intrinsic nature of quantum spin. Based on 45° geometric stability, hierarchical cosmic growth, and the photon as the 4D growth axis, this work establishes the complete axiomatic, mathematical, and physical core of the unified framework.
