Key Points

The research aims to present a cosmological model based on the properties of rotating black holes.
Developed a theoretical model linking observable universe parameters to black hole spin
Analyzed the implications of the dimensionless spin parameter α
Derived equations for dark energy equation of state and graviton mass
Proved that α determines cosmological parameters including dark energy and stability
Predicted a dark energy equation of state of w = -1.1225, matching observational data
Identified CMB anomalies as evidence of inherited rotation axis from the progenitor universe

Abstract

I propose a cosmological model in which the observable universe is the interior of a Kerr rotating black hole belonging to a parent universe. A quantum bounce near the Cauchy horizon produces a daughter universe inheriting the dimensionless spin parameter α of the progenitor. We prove that α alone determines all observable cosmology: the dark energy equation of state w = -(1+α²), the stability invariant Ψ = 1, graviton mass, and quantum uncertainty. At α = 0.35 the theory predicts w = -1.1225, consistent with DESI DR2 (w = -1.12±0.05). CMB anomalies arise as imprints of the inherited rotation axis. The MOND acceleration scale a₀ = α²H₀c is derived geometrically.
