General Outline of PFUS Primitive Field Unified Steady‑State System: Dynamic Evolution, Structural Fusion & Expansion, Information Coding and Origin of Time

This paper presents the general outline of the Primitive Field Unified Steady‑State (PFUS) system, and strictly distinguishes between the Universal Cosmos and the 4‑Dimensional Universe. The Universal Cosmos is a multi‑layered topological fluid‑gaseous entity, boundless, beginningless and endless, with inherent motion and no First Cause. The 4‑Dimensional Universe is subordinate to it, where all dynamics, evolution, time and structural unfolding occur. Based on double‑cone topology and sevenfold symmetry, this paper systematically expounds four core pillars: dynamic evolution driven by hierarchical difference and endogenous force, structural fusion and expansion within 4‑Dimensional Universe, information coding with β₁ primitive field interval and implicit constraints, and time origin as an endogenous process quantity generated by manifest‑latent oscillation. The PFUS system forms a universally closed, logically self‑consistent and presupposition‑free meta‑theoretical framework, which unifies the fundamental mechanisms of motion, structure, information and time, and provides a unified foundation for cosmology, physics and complex system research.
