Question:
I need to know if gravity can bend light, can gravity speed up light, what light is made of, and can it be possible that gravity some how be faster than light??


Replies:
Gravity does bend light. It does not speed light up, though it does change light's frequency. (Like anything else, light gains energy when it falls in a gravitational field.) Perturbations of a gravitational field are said to move at the speed of light, though I don't know how carefully this has been measured.
