The shift of light toward the red end of the spectrum when it is near a black hole is caused by _____.

Question

Quizplus · Accepted Answer

The gravitational red shift is a phenomenon predicted by the theory of general relativity, where light moving away from a massive object (like a black hole) is shifted towards the red end of the spectrum due to the gravitational pull of the object. This effect is a direct consequence of the warping of spacetime by gravity.
