Localized Geometric Friction and Cosmological Birefringence Signatures in Starburst Galactic Winds: An Empirical SPH Framework under the Field Dynamics Conjecture

We present a comprehensive Smoothed Particle Hydrodynamics (SPH) local simulation frameworkextending the Field Dynamics Conjecture to the macroscopic domain of starburst galaxies,specifically calibrating the models against the galactic wind of M82. Operating under a staticconoidal helicoidal metric governed by Einstein-Cartan-Sciama-Kibble (ECSK) gravity, we substitutephysical dark sectors with intrinsic spacetime torsion tensors and contorsion gradients. Byinjecting a divergence-free three-dimensional turbulent field (δX) at t = 0, we track its evolutionacross a non-metric KDK implicit integrator. The simulation dynamically confirms the topologicalpredictions of The Skateboard Theorem: arbitrary non-linear perturbations experience an absoluteglobal contraction, decaying exponentially as V (δX) ∝ exp(−σt) without relying on standardmolecular viscosity. Concurrently, the non-minimal coupling between the torsion trace vector Sμand the electromagnetic field tensor generates a localized, anisotropic cosmic birefringence signature(Δα) mapped along the dense gaseous filaments. Applying an intercontinental inter-particle MarkovChain Monte Carlo (MCMC) error calibration pipeline with a partial sky fraction of fsky = 0.7794,we demonstrate that next-generation spectropolarimetric surveys can isolate the quantum-geometriccoupling factor βanom with an empirical significance threshold exceeding 16.12σ, offering a definitive,falsifiable alternative to the concordance ΛCDM paradigm.
