Topological Dynamics of Gravitational and Electromagnetic Interactions via Spatial Superfluid Tensors: A Unified Hydrodynamic Master Equation for Gravity and Electromagnetism

The schism between General Relativity and Quantum Field Theory drives the 10^42 hierarchy problem and precision measurement anomalies. We propose Spiral Space Dynamics (SSD), remodeling the vacuum as a 5-dimensional chiral superfluid continuum. By projecting a 5D Unified Action into a 4D hydrodynamic equation, fundamental constants (G, ₀, ₀) emerge geometrically, eliminating the hierarchy gap. Furthermore, we derive a universal spacetime viscosity, ₃₄ₕ 45. 679 ppm, from topological symmetry breaking. This parameter-free invariant quantitatively resolves the HUST-2018 gravitational discrepancy, Muon g-2 mass-squared distortion, and Casimir boundary dissipation. Finally, SSD reduces the Schwarzschild metric to a singularity-free acoustic horizon and predicts Spacetime Cavitation Radiation (SCR), offering a falsifiable test for the cosmic continuum.
