This paper presents the "Material Space Theory" (MST) as a phys-ical alternative to the geometric abstraction of General Relativity. I argue that space is a material medium that flows and accelerates to-ward mass. By identifying the velocity of space with the escape veloc-ity and accounting for length contraction, I derive the Schwarzschild radius, gravitational time dilation, light deflection, and orbital pre-cession. Crucially, I demonstrate that the accelerating expansion of the universe results from stellar mass loss reducing the inward spatial flow, providing a physical basis for the Hubble constant (H₀), and that galactic rotation curves are explained by the vortex motion of material space.
