Model H: A Superfluid Mechanics Framework for Unified Cosmology

Model H presents a theoretical framework unifying physics from the proton to the observable universe through a single geometric parameter: the saturation tension δ = 0.0947%. Central hypothesis: The observable universe, when compressed to Planck density, occupies a volume corresponding to that of a proton, with a geometric discrepancy of 0.0947%. This residual tension governs cosmic dynamics at all scales.
