Z.I.P.P.E.D.: A Geometric Field Theory of Spatiotemporal Equilibrium and Galactic Dynamics

This manuscript presents a novel mechanical framework for the study of spacetime dynamics and galactic phenomena. The approach models spacetime as an elastic continuum with intrinsic scaling properties, providing predictive insights into galactic rotation, early universe structure formation, and cosmological scale tensions. The work includes a systematic derivation of the fundamental scaling constant, empirical validation against observational datasets, and applications to large-scale cosmological structures. This version is restricted and serves as a formal academic record.Keywords / Hashtags (IP-safe / Zenodo-style):Elastic SpacetimeMechanical CosmologyGalaxiesRotation CurvesCosmological TensionsPredictive FrameworkObservational Validation
