Abstract Einstein's general and special theories of relativity have laid the theoretical foundation for the laws of global cosmic motion, but they have long lacked a clear disciplinary positioning. Zhou Unified Stability Theory (ZUST), as an original global stability judgment theory, has filled the core gap in the research on the laws of cosmic stability. Based on the practical pain points of modern cosmology research, the demand for improving the disciplinary system, and the practical value of theoretical dissemination and application, this paper first clarifies the core motivation and necessity of disciplinary definition and relationship clarification, then conducts a dual definition of the two core disciplines in the field of cosmology, "Cosmokinetics" and "Cosmostability", clarifies their hierarchical relationship, theoretical foundations and dual logic, and constructs a global analytical closed loop of "motion description - stability judgment". The research shows that Cosmokinetics is a branch of kinematics formed by the author's disciplinary definition and expansion of application scope, with the theory of relativity as the core theoretical foundation. Its naming accurately matches the global influence and core functions of the theory of relativity, and is not an elevation or modification of the theory of relativity. Cosmostability is a core branch of stability science defined by the author, with ZUST as the only core theoretical entity, forming a parallel and dual relationship with Cosmokinetics. The two are equal in hierarchy, independent in research dimensions and complementary in functions, which together improve the cosmic disciplinary system and provide a complete theoretical framework and disciplinary support for global cosmic analysis. Update 1: Disciplinary Relationship Definition and Value Empowerment of Zhou Unified Stability Theory (ZUST) and Einstein's Theory of Relativity (Beijing Time 16:04, 2026-02-27 | Lunar Calendar 2026-01-11 | Author's Birthday) With the finalization of the core preprint of ZUST and the two sister working papers, this paper carries out a special disciplinary definition work to address readers' questions about the core relationship between ZUST and Einstein's Theory of Relativity. The core goal is to solve the core pain point of "strong theories but weak positioning" for the two theories, and to improve the disciplinary system boundaries of kinematics, stability science, and cosmology. 1. Core Disciplinary Definition (Name-only definition, no theoretical modification or replacement involved, with term originality explanation) Define Einstein's General/Special Theory of Relativity as Cosmokinetics: Though the term has been used in academic circles, this paper first clarifies it as the exclusive disciplinary positioning of the Theory of Relativity, anchoring its core value of "global cosmic motion description"; Define Zhou Unified Stability Theory (ZUST) as Cosmostability: The term is originally proposed in this paper, exclusively matching the disciplinary positioning of ZUST, clarifying its core positioning of "global cosmic stability judgment", and forming a dual framework with Cosmokinetics. 2. Core Value of Single-discipline Definition Cosmokinetics (Relativity): Fills the gap in disciplinary positioning, reduces the cost of cross-domain cognitive dissemination, and delineates a clear interface for its dual complementarity with ZUST. Cosmostability (ZUST): Grants exclusive disciplinary attribution to the original theory, simplifies the threshold for dissemination and application, and realizes the cosmic-scale global extension of stability science. 3. Dual-discipline Overlay Empowerment and Core Vision The two disciplines construct a global research closed loop of "motion description – stability judgment". This not only standardizes the disciplinary logic of cosmic research but also improves the efficiency of solving century-old cosmological problems such as dark matter and black holes. At the same time, it provides theoretical guidance for target selection and data interpretation of observation equipment such as FAST and JWST, forming a virtuous cycle of "theoretical prediction – observational verification – law summary". This paper clarifies the core relationship between the Theory of Relativity and ZUST: parallel, complementary, and mutually empowering. Their overlay can simultaneously solve the two core problems of "describing celestial motion laws" and "judging the stable nature of celestial bodies", forming a new analytical paradigm of "dynamic-static integration". This disciplinary synergy of "law + stability" will achieve a qualitative leap of "1+1 > 100", providing a new theoretical basis and research direction for human cosmic exploration.
