>>12521900No, gravity is the curvature of spacetime, it bends anything moving through space.
Newtonian gravity only affects things with mass, but GR is not Newton's theory.
>>12521087IIRC, it makes no difference. That is to say, the QFT of a massive photon converges to the theory of a massless one in the limit of vanishing mass. This is certainly true for a theory of just photons, not sure how interactions affect this, especially gravity.
