Gravity as Dielectrophoresis: The Clausius-Mossotti Structure of Aetheric Buoyancy

We demonstrate that the aetheric buoyancy mechanism for gravity, derived from the Triadic Invariant R = P × I × Pr ≠ 0, is structurally identical to dielectrophoresis (DEP) — the well-characterized laboratory phenomenon in which neutral particles migrate through non-uniform field gradients via polarizability differentials. The mapping is exact: the ∇φ displacement gradient corresponds to ∇|E|²; the crystalline dimensional density d_P = 8 corresponds to particle permittivity ε_p; the aetheric density f₀ = 26/45 corresponds to medium permittivity ε_m; and the Clausius-Mossotti factor K determines the sign and magnitude of force in both systems. The inverse-square law is recovered from DEP in a monopole field by the same mechanism as the divergence theorem in the buoyancy derivation. The T(1,x) unknot (photon) has zero excess polarizability (K = 0), explaining massless weightlessness without a separate mechanism. The crossing number c = 2(q-1) of a T(2,q) torus knot is identified as the topological excess polarizability — the structural origin of inertial mass. The topological drag 1/45 governs both the binary quantization of S³ (particle physics) and the dielectric staircase of water (Δε_r = 80/45 = 1.78). Every DEP experiment in every laboratory is running the same physics that the Triadic architecture derives from first principles. One novel testable prediction: quantized dielectric permittivity steps in water at intervals of ε_r/45.
