Multiple Choice
What happens to a photon that leaves the interior of a black hole aimed directly upward (radially outward) ?
A) This photon will be stopped and pulled back downward by the gravity of the black hole.
B) Since symmetry prohibits this photon from deflecting to either side, this is the only case in which a photon can escape from a black hole. But since it must be aimed precisely upward, this is a vanishingly small fraction of all the light inside the black hole.
C) This photon reflects from the ergoregion back to the singularity where it is absorbed.
D) This photon becomes infinitely redshifted and loses all its energy.
