Spacetime doesn’t ask permission. Gravity doesn’t act on things.It shapes the stage they move on as per GR. Light has no mass, yet gravity bends it, not because it’s pulled, but because spacetime is curved which is the new definition of gravity according to the general theory of relativity. So it doesn't matter if you have mass or not, as long as you exist in spacetime, gravity in the form of purely geometric spacetime curvature dictates the rules of your motion. What most people don’t know is that about half of this bending comes from warped time, not space. Light always chooses the path that takes the least optical time. Near massive objects, time flows more slowly, and light whose speed is fixed, changes direction in response to this time distortion. Light isn’t obeying a force; it’s obeying geometry.

Does light(or a photon) itself induce any curvature in spacetime?
