Alignment Threshold Time (ATT) is introduced as a dimensionless scalar resolution field providing an alternative interpretation of gravitational phenomena traditionally modeled through spacetime curvature. In this framework, physical proper time is modulated via dτ=T(x) dt, where T(x) is a scalar field governed by a covariant wave equation sourced by mass density. Electromagnetic propagation is described using an effective refractive index n(x)=1/T(x), replacing null geodesics with Fermat-based propagation. In the weak-field static limit, the model recovers first-order predictions of General Relativity, including gravitational redshift, light bending, and Shapiro time delay, without invoking intrinsic metric curvature. The scalar field equation reduces to a Poisson-type equation consistent with Newtonian gravity. Geometry is interpreted as an emergent representation of spatial resolution gradients rather than a fundamental property of spacetime. A proposed quantum measurement experiment is outlined to independently test resolution dynamics. This work presents a scalar-field reinterpretation of gravitational phenomena consistent with weak-field observations and invites further investigation into nonlinear strong-field extensions.
