Singularity Resolution via Relativistic Spin Hydrodynamics: A Proposed Deterministic Framework for Einstein–Rosen Bridges

We present a mechanism to resolve curvature singularities relying strictly on the Standard Model within a conventional 4D spacetime manifold. By treating the quark-gluon plasma (QGP) within the framework of second-order relativistic spin hydrodynamics, we propose that the divergence of resonant bulk viscosity near the QCD phase transition, coupled with the minimal Einstein-Cartan spin-torsion interaction, provides a hydrodynamic mechanism for geodesic completeness. We show that the Chiral Battery mechanism creates a population inversion of spin states, driving the core into a spin-thermodynamic Negative Absolute Temperature regime. This generates a stabilizing spin-torsion geometric stiffness that arrests the collapse into a stationary, supersolid Einstein-Rosen bridge, satisfying the generalized Israel junction conditions while preserving global unitarity and information conservation. The resulting solution describes a regular, non-singular interior geometry consistent with a deterministic, globally hyperbolic spacetime. ----- Version 3.0 Change Log: • Expanded Bibliography: Added foundational references (including Hawking, Kibble, and Abrikosov) to support the core theoretical framework. • Precision Citations: Micro-targeted the inline citations to anchor specific references to key details and mechanisms within the body of the text.
