Emergent Metric Viscosity from Chiral Anomalies: Lagrangian Formulation.

This paper establishes the theoretical and empirical foundation for the metric viscosity coefficient (K_0). Responding to the need for a rigorous first-principles derivation, we present the effective field theory Lagrangian where K_0 emerges from the spontaneous breaking of Lorentz invariance in highly vortical manifolds. Furthermore, we provide explicit numerical predictions for the Hubble parameter H(z) to be tested by upcoming JWST observations, and outline the exact solid-state Hamiltonian for Direct Energy Conversion (DEC) in TaAs Weyl semimetals without ad hoc parameters.
