Torsional Topology and the Kerr Horizon: Hydrodynamic Unification of the Dark Sector, Resolution of the Hubble Tension, and Emergent MOND

The current theoretical impasse of the Λ-CDM model, highlighted by the failure of dark matter direct detection programs and growing cosmological tensions, requires transcending particle reductionism in favor of a purely geometric and relational paradigm. In this twentieth research paper, we present a comprehensive hydrodynamic unification wherein the observable Universe is confined within a parent Kerr Horizon, originating from a non-singular Einstein-Cartan-Sciama-Kibble (ECSK) bounce. The dark sector is dismantled as an autonomous particle entity: "Dark Matter" is redefined as the macroscopic fossil trace of the primordial fluid, an ultra-light superfluid condensate (mχ ≈ 10-21 eV) sustained by inherited quantized vorticity. The empty topological core of this vortex serves as a quiescent chimney and trigger for baryonic Jeans gravitational instability, resolving the genesis of Supermassive Black Holes (SMBHs). The resonant disk-halo coupling in the solitonic limit of the condensate asymptotically reproduces the critical acceleration a0 and the Baryonic Tully-Fisher Relation, reclassifying MOND as a rigorous emergent fluid property. Concurrently, the necessity for Dark Energy is eliminated: cosmic acceleration is demonstrated to be the exact superposition of holographic horizon vacuum tension (V0) and differential centrifugal expansion derived from the Raychaudhuri equation. This asymmetric expansion analytically resolves the Hubble Tension (H0) as a consequence of our local kinematic embedding in an equatorial flow. Finally, treating the topology as an open system, large-scale anomalies (Cosmic Bulk Flows / Dark Flow, CMB Cold Spot) find a direct causal explanation in the entropic injections and topological shocks (ringdown) induced by the multiverse ecology. The model provides an exact falsifiability bridge through the prediction of primordial parity violation (non-zero TB and EB cross-spectra) in the stochastic gravitational wave background, detectable by forthcoming space-borne observatories (LiteBIRD, LISA, DECIGO).
