Anchored Expansion Theory (AET) proposes that gravity arises from resistance to the forward flow of time, modulated by mass, rather than from spacetime curvature. In this framework, cosmic expansion is identified with a literal propagation of space into the future. We construct a relativistic field theory where this resistance is mediated by a scalar field φ, derive its field equations, and analyze the Newtonian and cosmological limits. AET naturally reproduces gravitational acceleration, late-time cosmic acceleration, and matches observational data on H(z), structure growth, and redshift-space distortions without invoking dark energy. These results suggest AET may offer a viable alternative to ΛCDM cosmology.
