A speculative cosmological framework proposing that the observable universe exists at approximately the seventh level of a ten-level recursive chain of nested black hole interiors (the "chute"). The model derives unified explanations for dark matter (primitive matter inherited from upstream levels), cosmic inflation (interior perspective of black hole formation), dark energy (cascading brane stress from downstream universe creation), force emergence (compound interactions shaped by chute geometry), quantum indeterminacy (observational distortion from pressurized spacetime), the nature of particles (vortices in the spacetime medium), and the speed of light as a depth-dependent material property of the medium. The framework addresses eighteen open problems in modern physics, including: the hierarchy problem (resolved via chute depth compounding), the cosmological constant problem (resolved — QFT vacuum calculation identified as wrong physical model), the Hubble tension (resolved via variable c, dynamic dark energy, and evolving matter ratio), dark matter non-detection (resolved — upstream matter not native to our force physics), JWST impossibly early galaxies (expected — inherited dark matter scaffolding), matter-antimatter asymmetry (resolved — inherited parent black hole spin), quantum gravity incompatibility (dissolved — identified as category error applying downstream tools to upstream phenomena), fine-tuning of physical constants (resolved — depth-tuning not fine-tuning), three fermion generations (resolved — vortex harmonics), the dark energy coincidence problem (resolved — causally coupled quantities), and multiple dark matter observational tensions including the cuspy halo problem, too-big-to-fail problem, and rotation curve diversity (resolved — multi-type dark matter from different upstream levels). The ten chute levels correspond to the ten dimensions required by string-theoretic formulations, reframing extra dimensions not as compactified spatial dimensions but as entire upstream and downstream universes. E=mc² is derived as a natural vortex energy relationship in a pressurized fluid medium. The model predicts a dynamic dark energy equation of state (w ≠ −1) testable by DESI and Euclid, correlations between dark energy onset and black hole formation history, variable fine structure constant at high redshift, fourth-generation fermion instability, and specific JWST structure formation signatures. Connections are identified to Einstein-Cartan torsion theory (Popławski), Kaluza-Klein dimensional reduction, AdS/CFT correspondence (Maldacena), superfluid vacuum theory (Volovik), de Broglie-Bohm pilot wave mechanics, variable speed of light cosmologies (Magueijo, Moffat), the weak gravity conjecture (Arkani-Hamed et al.), and Kelvin's vortex atom hypothesis.
