Dynamic Gravity Theory: A Relativistic Framework for Explaining Galactic Dynamics Without Dark Matter

This work introduces *Dynamic Gravity Theory*, a novel relativistic framework that redefines gravity as an emergent phenomenon shaped not only by mass but by spatial gradients in kinetic energy. By modifying Einstein’s field equations, the theory accurately predicts galactic rotation curves—such as for NGC 3198 and NGC 2403—without invoking dark matter. The model also addresses conceptual inconsistencies in general relativity regarding the origin of spacetime and provides a bridge to quantum interpretations of gravity. Developed independently, this research aims to open new dialogue about the nature of spacetime and motion-based curvature.
