The Misunderstanding of the Nucleosynthesis Endpoint: From the Kinetic-Potential Mismatch to the Generalization of the "Local-to-Universal" Mode of Thinking

There exists in classical physics an insufficiently examined mode of thinking: taking local relations that hold only under specific conditions and promoting them, without declaration, to universal laws. This paper argues this pattern through two typical cases: first, the mismatch in classical gravitation between F = GMm/R² and F = mg, which leads to g = GM/R² being treated as a universal definition; second, in astrophysics, the special stability of iron in the standard nucleosynthesis path being generalized into the absolute conclusion that "all stellar nucleosynthesis stops at iron." Based on the World Quantum Theory (WQT) framework, this paper reveals the homology in logical structure between these two cases — both are mismatches between quantities from the kinetic framework and quantities from the potential framework, or the treatment of a local phenomenon valid under specific energy conditions as an absolute boundary of the universe. This paper points out that this "local-to-universal" overgeneralization is a deep methodological flaw in classical physics, rooted in the neglect of condition declaration and the reification of model-dependent conclusions.
