Dual-Layer Light Invariance: The Open-Close Structure of Ma as a Complete Theory of Phi2 Perturbation — Paper 1 of 3D Theory Series

This paper is part of the TheYKHC Theoretical Series: 'From Duality to Field: A Three-Dimensional Evolution of Universal Theory' Paper 1: Dual-Layer Light Invariance (2D — The Discovery of Duality) Paper 2: Why Spacetime is (3+1)-Dimensional (2.5D — Polygon Transcendence) Paper 3: Ki-Net Field Evidence (3D — Universal Field Completion) Related: Genki Particle Dance (DOI: 10.5281/zenodo.20955834) The series demonstrates that V = N / D governs reality from the quantum vacuum to the cosmic scale. [Paper 1 of 3 — 2D: The Discovery of Duality] Light is simultaneously wave and particle. This is not a paradox — it is the signature of a dual-layer universe governed by V = N / D. This paper presents the Open-Close Structure of Ma (間) as the fundamental mechanism behind wave-particle duality, demonstrating that phi2 perturbation is the mathematical expression of a universe that oscillates between coherence (N) and dispersion (D). The dual nature of light is the first empirical proof that V = N / D operates at the quantum scale.
