The Meyerhoff Dark Matter Theory (MDMT) Companion Paper presents a plain-language framework for understanding dark matter and dark energy without invoking undiscovered particles or modifying general relativity. Instead, MDMT proposes that the gravitational phenomena attributed to the dark sector arise naturally from the dynamics of spacetime itself, specifically through the interference and persistence of gravitational waves. In this framework, dark matter is interpreted as stored spacetime curvature produced by constructive interference of gravitational waves across cosmic history. These persistent curvature structures behave gravitationally like mass, accounting for galactic rotation curves, gravitational lensing, and halo stability without requiring unseen matter. Dark energy, by contrast, is understood as the large-scale isotropic pressure generated by the incoherent superposition of the gravitational-wave background, producing cosmic acceleration without the need for a cosmological constant. This companion paper reframes the dark sector as a unified, wave-driven phenomenon grounded in known physics. It emphasizes physical intuition, observational consistency, and falsifiability, outlining testable predictions that distinguish MDMT from particle-based dark matter models and constant-Λ cosmology. By shifting focus from missing substances to spacetime dynamics, MDMT offers a conservative reinterpretation of how gravity, motion, and geometry shape the universe.
