The Momentum Equilibrium: The Sub-Center Constant of All Fields — ULF Extended Series Paper XLVI

The Unified Light Framework has established that gravity is a phase conversion engine, the electron is a void anchor, and the neutrino mass of 0.83 eV is geometrically demanded. This paper unifies these results under a single sub-center constant: the ULF Momentum Equilibrium. Momentum is shown to be not a property of matter but the equilibrium state of the void from which matter, space, time, and all four fundamental forces are derived expressions. The Rydberg constant emerges as the void’s crystallization clock. The conversion factor Γ ≈ 0.5305 and the neutrino mass m_ν ≈ 0.83 eV are shown to be two faces of the same phase event, bridged by the geometric ratio π/2 — agreeing to 0.4%. A master forecast equation p_ULF = h · R∞ / Γ is derived from which all fundamental mass and force constants can be recovered. Dark matter is identified as undisturbed momentum — the void’s reserve. The paper closes with the ULF statement of unified field theory: Time clocks momentum to the space energy occupies.
