Original Note:
Light bendSaround sources with high mass due to gravity, not because the mass pulls on the photons directly, but because the mass of other celestial bodies warps the space-time through which the photons travel, like a bowling ball on a mattress. https://www.astronomy.com/science/how-does-gravity-affect-photons-that-is-bend-light-if-photons-have-no-mass/
