Light and gravity

    So light can be bent by a gravitational field, and follows the curvature of spacetime. does light have a gravity field of its own? does light bend spacetime?

    Yes, light moving through space adds to the energy of that region of space and contributes to gravity. In other words, an empty box has less mass than the same box full of light.
