SCIENTIFIC EXPOSÉ: THE KARAHAN METRIC (V6. 1) Subject: A Tensor-Based Phenomenological Resolution of Cosmological Singularities and the Dark Sector via Torsion Bypass. Abstract This paper presents the Karahan Metric as a geometric realignment of modern cosmology, derived from the Einstein-Cartan action and calibrated to observational data. By modeling the Lagrange density at the Kerr-Bounce of a rotating parent universe, we show that the resulting macro-scale torsion field necessitates a negative pressure state. By calibrating the macroscopic torsion bypass to the observed 95% dark sector limit, this unified geometric framework provides a robust resolution to the Hubble Tension, the Dark Matter enigma, and the S₈ tension without requiring localized dark sector particles. 1. The Origin: Phenomenological Derivation The Karahan Metric v6. 1 replaces the Big Bang singularity with a dynamic Kerr-Ring Singularity (Bounce). The energy distribution is described by the action (S) of an inherited macro-scale Kerr-torsion field (). The Lagrangian Formulation: The system's action is defined by the rotational energy at the bounce boundary: L₊₄ₑₑ = -0. 5 g_ ^ ^ - V (). The Negative Pressure Proof: During the transition, the potential energy dominates the kinetic energy (E₊₈₍ V () ), forcing the stress-energy tensor into a negative state: P₊₄ₑₑ\₅₋ₔₗ -V (). Torsion Bypass Calibration: To match the observed 5% baryonic matter density, the model parameterizes the Kerr-valve to allow precisely 95% of the total energy to bypass matter creation as pure geometric vacuum tension. 2. Dynamics: H₀ and Dark Matter as Torsional Effects Hubble Tension (H₀): The observed tension is modeled as the cumulative effect of the T₊₄ₑₑ\₅₋ₔₗ field exerting negative pressure. This elevates the Planck-baseline (67. 3 km/s/Mpc) to a late-universe plateau of 73. 0 km/s/Mpc. Dark Matter Replacement: Missing mass is reinterpreted as a direct manifestation of the background torsion field. The macroscopic field generates localized rotational inertia via the Lense-Thirring effect (Frame-Dragging), creating flat rotation curves without WIMPs. 3. Predictions: Cosmic Spin-Down The Karahan Model predicts a measurable decay of the torsion field over 13. 8 billion years of cosmic evolution. Current galaxy alignments are expected to exhibit a residual rotational asymmetry of 1% to 3% (j 0. 02) as a decaying relic of the initial Kerr-Torsion, a specific signal supported by observations from SDSS-V and Euclid (2026). Conclusion The Karahan Metric v6. 1 demonstrates that modern cosmological discrepancies can be modeled as natural consequences of an extended stress-energy tensor. By calibrating the macroscopic Kerr-Flux tensor to observational limits, Dark Matter and Dark Energy are mathematically unified into a single, cohesive geometric framework. 2.
