Phase Closure as the Origin of Quantization, Spin, and Stability in the Methane Metauniverse (MMU)

This article presents a geometric and topological framework for atomic and nuclear structure based on the Methane Metauniverse (MMU). Physical systems are described as closed standing wave modes supported by a tetrahedral UR-cell geometry. Quantization, spin-1/2, orbital structure, atomic binding, and nuclear stability emerge as necessary consequences of global phase closure rather than as independent postulates. Electron–proton binding is explained as a joint phase-closed configuration, providing a structural reason for atomic stability. The MMU field equation is formulated on closed loops, clarifying the origin of discrete spectra and the role of spinorial topology. All results are developed within a canon-constrained, auditable methodology with explicit assumptions and reproducible structure.
