Elaboration of the Feynman Path Integral via the Unified Scale Symmetry Model (USSM): The Feynman-Santos Tensors

This paper presents the formal derivation of the Feynman-Santos Tensors, providing a deterministic, fluid-dynamic basis for the Feynman Path Integral. Within the framework of the Unified Scale-Symmetry Model (USSM), the quantum 'sum over histories' is reinterpreted as a physical sum over superfluid streamlines governed by a 17.135 Gyr universal metric. By incorporating the Universal Viscosity Constant (sigma = 0.007716) and the Bulk Viscosity of the Vacuum (zeta), we provide a mechanical explanation for vortex path selection and particle generation. The tensors predict discrete metric resonance nodes where matter-vortices undergo laminar-to-turbulent phase transitions, offering a new predictive roadmap for reconciling Quantum Electrodynamics (QED) with a viscous General Relativity.
