Convergent Mathematical Foundations of Hydrodynamic Quantum Gravity - Seven Independent Frameworks, One Physical Reality

The Standard Model of particle physics contains a set of empirically fixed inputs—particle masses, mixing parameters, and coupling constants—that are not derived within the model’s present formulation. This preprint surveys a programme of structural correspondences in which several mathematical frameworks, developed independently and for unrelated purposes, reproduce patterns that resemble Standard Model regularities (e.g., hierarchical spectra, three-family structure, and mixing behaviour). The aim is comparative and evidential: to state each proposed mapping explicitly, distinguish strict identities from analogies or parameter-matched correspondences, and identify where the programme remains incomplete.…
