    True. The em field is significantly more energetic, meaning that it contributes more to the stress energy tensor than the force of gravity

    But recall that the force of gravity is the momentum change “due to” the curvature of spacetime. The fact that the force of gravity can bend spacetime at all is a really weird second-order perturbative effect.

    These perturbative effects are typically described with a quantum field theory, but gravity has been thus far notably difficult to quantize.

      But didn’t you just say that the electric field curves it too?
