Physics constants are echoes of absence. I present a framework deriving fundamental constants from four void positions - orphans in a relational manifold that can be mapped to but never from. From this seed set {2, 7, 8, 11}, I generate the fine structure constant (10⁻¹⁰% precision), Barbero-Immirzi parameter (10⁻⁵%), proton-electron mass ratio (10⁻⁸%), and Newton's gravitational constant (10⁻⁸%). The framework predicts 13+ constants with geometric mean error below 10⁻⁵%. A critical identity, T(11) + 2 = T(16)/2, reveals that gravity "bisects" electromagnetism - the apparent weakness of gravity is geometric, not dynamical. The same structure predicts molecular conformation frequencies to 89% accuracy. Constants are not arbitrary; they are what measurement sounds like when the void speaks.
