What Happens to a Photon That Leaves the Interior of a Black

question 201

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 ceases to exist.
