Unified Granular Framework: Emergent Matter, Geometry, Gravity, Dark Sectors, and Cosmology

We propose a unified granular framework in which matter, radiation, spacetime geometry,gravity, dark matter, and dark energy emerge from a common microscopic substrate.No fundamental distinction is assumed between content and container: energy, matter, andspacetime correspond to different collective regimes of the same underlying structure.A saturation-driven refinement mechanism generates geometric degrees of freedom and induceseffective gravitational dynamics. Cosmic expansion, dark energy phenomenology, andstructure formation arise from energy–geometry exchange.We show that General Relativity is recovered as a strict limiting case, while deviations producequantitative signatures in weak lensing, growth of structure, and gravitational-wave emission.The framework reproduces current constraints on H0, S8, and GW efficiencies within a minimalparameter set. Remaining open problems concern the non-equilibrium kinetics of refinementand its renormalization behavior.
