This is Version 4.3 (Part 3) of the Unified Conical Cosmos Model series, the quantum-gravity and cosmic unification extension of the system. Building on the 4-Dimensional Cosmic Growth Theory and Bi's Pythagorean Cone Platform, and the full framework of V4.1 (Part 1, full version) and V4.2 (Part 2, concise edition), this work provides rigorous causal-geometric explanations for spacetime, quantum entanglement, gravity, dark matter, and dark energy. Together with V4.1 and V4.2, it forms a complete, self-consistent, parameter-free unified theory bridging quantum mechanics and general relativity, completing the full theoretical system of the Bi's Pythagorean Truncated Cone Model.
