: : My 10 year old niece has a science question from her teacher. Does gravity affect light, and can it be bent? : : Any help would be great. : You, physically, cannot bend light, yet if light is passing a mass of great quantity, the mass of the light : will be accelerated by the large mass, and the light will be in the direction of the mass. The amount of bend in the : beam of light may not be notible, but there will always be a slight bend in the light if it is being accelerated by another mass.
