Recently, I was thinking about the nature of reciprocity in some cases of natural phenomenon, for example, Newtons Thrid Law of Motion, or, Faraday's Law of Induction. Considering that spacetime distortion, due to a gravity field, leads to a change in the light path, or, a change in light velocity, when observed from a region with diferent spacetime metric. Would a induced change in light velocity, induce a distorion in spacetime (to keep c constant at local reference), thus, generating gravity? And, lets consider that the propagation of the light (in vacuum) would be distorted (or have its aparent velocity changed) by some hypothetical advanced technology. It's the opposite direction of: Mass > Gravity > Spacetime distortion > Light distortion. Where, a induced light distortion would create: Light distortion > Spacetime distortion > Gravity Note that the spacetime warp would happen because c must be constant. Is this idea consistent? Is there any current model describing this?
