PARENT-PROGENY KERR BLACK HOLE – 4D FRACTAL COSMOLOGY (PPKBH-4DFC)

Executive Abstract Modern institutional cosmology faces an intensifying foundational crisis. To rescue an expanding, big-bang manifold from observational contradictions, the Standard Model (CDM) relies on a succession of unverified auxiliary hypotheses: an inflationary scalar field to enforce horizon uniformity, non-baryonic particulate Dark Matter to hold galaxies together, and a cosmological constant ( / Dark Energy) to drive late-time cosmic acceleration. This manuscript establishes a complete, self-contained physical replacement: the Parent-Progeny Kerr Black Hole – 4D Fractal Cosmology (PPKBH-4DFC) and Nucleon Metric Tension (NMT) framework. Developed as a descending-energy Sierpinski fractal continuum, PPKBH-4DFC demonstrates that our observable universe () is the bounded, oblate interior cavity of a rotating supermassive Kerr black hole (, ) located within a parent universe (). By replacing singularities with Fermion Spin-Torsion Gridlock and an Axiom Break (), the framework derives a rigorous physical solution to the cosmological timeline: The 6-Second Cold Start: A white-hole-style metric reversal executes a mass partition, sequestering of progenitor mass at the boundary shell to form the Machian inertia anchor. Then of the stellar core retracts to the event horizon shell is a 6-second pop. And finally, 10 e-17 of the 10% precipitates as baryonic matter within the progeny void. Simultaneous point-source hadronization and an endothermic "99% Gulp" vacuum-clearing trigger at cool the cavity to in , resolving the Cosmological Lithium Problem and slashing the Jeans mass thermal barrier by . Truncated Asymptotic Slack & Toth-Moffat Inertia: The formation of the parent Event Horizon severs the external asymptotic tail of the parent's gravity well, locking the initial Vacuum Elastic Tension (VET) floor in at capacity. This transiently decouples gravitational mass from inertial mass (), powering the frictionless Cold Avalanche and forming JWST's high- "Little Red Dots" and supermassive black holes without Dark Matter. Moffat & Toth’s finite-propagation shell integral confirms that bulk inertia () is the Machian drag of the boundary shell. The NMT Engine & The Hubble Tension: Nucleons ratcheting against the VET substrate bleed mechanical tension as broadband High-Frequency Gravitational Waves. This continuous work integral shallows local gravity wells into flat isothermal basins (eliminating Dark Matter) and stretches cosmic voids into a Buchert Timescape. Winding out the Truncated Asymptotic Slack over generates the Hubble Tension exhaust () and drives solar coronal heating via the Gertsenshtein effect. PPKBH-4DFC provides insight to a wide range of observational spectrum of astrophysics using zero Dark Matter, zero Dark Energy, and zero Inflation.
