The Efficiency Principle of Corridor Installation in the Space‑Phase Substrate: Unified Structure from Electron Shell to Galactic Spiral

This paper presents a unified transport principle within the SP3 framework governingmatter and energy propagation across scales, from electron confinement to galactic spiralstructure. The principle states that a participating substrate organizes into corridors ofcoherence to enable efficient transport while minimizing self‑disruption. Corridor geometryvaries according to transport conditions: linear propagation produces parallel bands,rotational drift produces spiral corridors, and rotational confinement produces closedorbital corridors. Laser diffraction, planetary orbits, electron shells, and spiral galaxies areexamined as manifestations of this universal coordination mechanism. The resultingframework provides a unified interpretation of structure formation across physical scale.
