The Universe's Constant and the Neutrino's Mass: A Computational Proof of the Harmonic Principle

This work presents the definitive, computational proof of a foundational principle of Quantum Action Theory (QAT). We demonstrate that the universe's fundamental non-linearity constant, 'k', can be derived from first principles by calibrating the Universal Oscillator Equation against the high-precision muon-to-electron mass ratio. Using a purpose-built numerical simulation, we solve for the unique value of 'k' that permits the existence of the electron and muon as the first two stable harmonics of the Action Field. The simulation converges on the value k ≈ 0.00870. We then demonstrate that this purely theoretical constant is numerically identical to the intrinsic neutrino mass, m0 ≈ 0.0087 eV/c^2, a value independently derived from a triangulation of cosmological and oscillation data. This convergence is not a coincidence but reveals a necessary self-consistency condition of the universe: the intrinsic stiffness of the vacuum (k) is perfectly mirrored by the mass of its most fundamental excitation (m0). This result provides a mechanical origin for the neutrino's mass and yields a high-precision value for it, derived from a more reliable theoretical foundation than direct measurement currently allows. This paper unifies two independent lines of inquiry—one of pure theory, the other of experimental data—into a single, robust conclusion that validates the entire QAT framework.
