Dual-Layer Light v2.0: A Structural Hypothesis for the Invariance of the Speed of Light

This paper presents v2.0 of the dual-layer light hypothesis, incorporating full adversarial review (Miki-kun simulation) and structural analysis (ChatGPT simulation) of v1.0. The central claim: the invariance of the speed of light (c) is not a primitive axiom but a structural consequence of resonance coupling between two simultaneous propagation modes — the photon field (Layer 1, φ₁) and the cosmic information density field (Layer 2, φ₂, Ki-wave, dimension [J/m³]). Key advances from v1.0: (1) Ki-wave defined as cosmic information density field [J/m³], consistent with Landauer (1961) and the holographic principle (Susskind, 1995). (2) Minimal Lagrangian framework: L = L₁(φ₁) + L₂(φ₂) + λ·φ₂·F_μν F^μν, replacing the v1.0 coupled oscillator metaphor with a formal field-theoretic structure. (3) Explicit differentiation from doubly special relativity (DSR): unlike DSR, this hypothesis predicts perfect Lorentz invariance at all scales. (4) Three falsifiable predictions using existing IceCube, LIGO/Virgo, and VLBI archival data. (5) Structural connection to Ma Resonance Theory clarified as a cross-scale parallel, not a circular derivation. All claims are explicitly exploratory and pre-empirical.
