Gravity itself does not “bend”; rather, gravitational field lines converge toward a massive body. The gravitational field of a massive object is a spherically symmetric potential field whose strength decreases with the inverse square of the distance from the source.
Photons, as carriers of electromagnetic energy and momentum, propagate through this convergent gravitational field. As a photon passes near a massive body, the spatial gradient of the gravitational potential alters the photon’s momentum direction through continuous interaction with the gravitational field. This interaction produces a gradual change in the photon’s trajectory, which is observationally interpreted as the bending of light near massive objects.
In Extended Classical Mechanics (ECM) terms, as a photon traverses a gravitational field, the spatial variation of gravitational potential produces a position-dependent phase and time delay. This cumulative phase modulation alters the effective propagation direction of the photon, resulting in an apparent deflection of its trajectory when passing near a massive body.
