Chute Cosmology: A Two-Medium Ontology for Mass, Gravity, Dark Matter, Quantum Mechanics, and the Particle Spectrum

This paper presents Chute Cosmology, a comprehensive framework proposing that the observable universe exists as one interior in a nested chain of black hole interiors—a branching structure called the Chute. The framework rests on a two-medium ontology: reality consists of two immiscible substrates, spacetime and brane, coexisting as an emulsion under pressurization. All physics emerges as interfacial mechanics in this two-medium system. The framework derives unified accounts of mass (as interfacial drag from compositional mismatch), gravity (as thermodynamic sorting driven by interfacial energy minimization), dark matter (as structural phase inversion producing brane-continuous regions invisible to spacetime waves), dark energy (as cascading brane failure), inflation (as brane expansion forming a new shell boundary), quantum uncertainty (as irreducible noise from dispersed brane droplets), and the quantum measurement problem (as brane activation in a hybrid medium). The mathematical architecture includes a hybrid field Ψ(x) = (φ(x), χ(x)), a coupled Navier–Stokes–Cahn–Hilliard PDE system, a hybrid action principle, and an emergent acoustic metric from which general relativity arises as a long-wavelength limit. The mass equation m = κ|χ − χ₀|/c² is derived explicitly from a Ginzburg–Landau free-energy expansion. The framework generates over a dozen falsifiable predictions testable by current observational programs including DESI, CMB anomaly analyses, and gravitational lensing surveys. A central implication is that elementary particles are survival-tested vortex-seed structures inherited from ancestor shells, potentially far older than our universe. If the Chute has no first shell, they approach eternity. This paper integrates and supersedes four earlier companion publications on Zenodo.
