TUM Paper 66: Densified Vacuum as Superfluid

We formalize the quantum vacuum as a structured superfluid in Cl(8,0). At the exceptional point sin²θ = cos²θ = 0.5 (θ_EP = π/4), a non-Hermitian transition to a NESS attractor occurs, defined by fundamental topological constants derived in Paper 64. The effective curvature becomes density-driven, yielding a universal U-signature y ∝ cosh(kx) that unifies optical mirages (Fermat) and gravitational lensing (Schwarzschild). MSW neutrino oscillation and galactic AGN cavitation are shown as frequency beating in the same medium. Cosmological bipolar flow (Dipole Repeller to Shapley) emerges as a macroscopic pressure gradient (∇P_cosmic) in this superfluid, with zero free parameters beyond the Cl(8,0) algebra.
