D-UQAL: The Unified Viscoelastic Framework of Spacetime

Abstract: The D-UQAL framework presents spacetime as a viscoelastic physical medium. Dark matter and dark energy emerge as effective manifestations of intrinsic fabric viscosity and stiffness. Thirty-two universal mechanical laws are formulated to connect quantum behavior, relativistic dynamics, and cosmic expansion. This research establishes a mechanical substrate underlying quantum and cosmological phenomena, replacing unknown entities with measurable fabric properties.
