When light passes a mass, the light path is bent due to the curvature of space caused by the object mass. Is there an inverse effect of bending a light path to cause an effect of generating a level of space curvature?
The answer is no. The metric generates the geodesic of the ray, not the other way around. The black hole would still bend spacetime even if there was no ray. The photon does bend spacetime though, but not enough to change the metric significantly.
