Khara, Alankar Sukhdev Singh: Complete Detectable Spacetime Geometry: Closure Sector Origin of the Galaxy Dynamics and the Hubble Tension

_SSRN_. forthcomingA unified description of gravitational phenomena across galactic and cosmological scales remains incomplete within the standard framework of General Relativity supplemented by dark matter and dark energy. In particular, the empirical regularity of galaxy rotation curves and the persistent, structured discrepancy between early-and late-universe determinations of the Hubble constant indicate the presence of underlying geometric constraints not captured by existing formulations.
