This work completes the formulation of the fluid-dynamic paradigm of physics, demonstrating that empty geometric spacetime must be replaced by a continuous, viscous fermionic condensate. By abandoning standard ΛCDM dogmas, the paper discloses the exact mechanical mechanisms governing particle formation and structural stability within a material vacuum substrate. The core framework focuses on two interconnected physical processes: first, the mechanics of viscous coupling, where cooling below the critical Shlyapik Threshold (55. 6 million K) activates macroscopic shear viscosity (η = 1. 2 × 10^−15 Pa · s), forcing independent ψ-fermions (4. 8 keV) into interlocking differential pairs to generate fundamental gauge bosons. Second, the mirror pressure of solitons, establishing the long-term stability of 3D-vortices (protons) via a sharp phase transition. As a soliton displaces the dense condensate, the elastic substrate responds with a local pressure inversion up to 0. 795 × 10⁹ Pa, creating a frictionless, vitrified defensive cocoon that analytically yields a precise proton radius of 0. 841 fm, perfectly matching experimental data.
