Cosmic Structural Self-Stability and the Inevitability of Celestial and Life Continuance Homology-Isomorphism Postulate and Deduction of Logical Ontology

This paper builds upon the fully closed theoretical framework of the Pythagorean Circular Platform System, the Logical Origin Theory, and the Four-Part Operational Laws. Taking logical existence as the fundamental ontological source of the cosmos, this work develops a systematic deduction of universal homology, structural isomorphism and cross-scale evolutionary synchronism. The research is grounded in self-consistent foundational postulates, mathematically defined steady-state threshold equations, and corroborated by established astronomical observational results. It is demonstrated that both microscopic fundamental units and large-scale macroscopic celestial architectures are governed by a unified underlying logical order. Microscopic and macroscopic entities share a common origin, follow isomorphic structural regulations, and evolve in synchronous coordination. Steady-state celestial configurations inherently possess structural robustness, external perturbation immunity, and an in-depth protective mechanism for the fundamental carrier of life. Within the observable four-dimensional cosmic domain, conventional astronomical outbursts and geological catastrophes are incapable of exceeding the critical threshold of systemic stability. With rigorous logical reasoning and solid observational corroboration, this paper completes the ultimate closure of the theoretical system and establishes the ontological conclusion that logic constitutes the cosmos, and the cosmos manifests itself through logic.
