An astronaut tosses a green ball toward a Schwarzschild black hole. Which of these will NOT be observed as the ball accelerates toward the event horizon?

Question

Quizplus · Accepted Answer

As the green ball accelerates toward the event horizon of a Schwarzschild black hole, it will undergo gravitational redshift, causing it to appear to change color from green to yellow to red (A). The ball will also appear to become elongated due to tidal forces stretching it along the direction of its fall (B), and its lateral size will decrease due to the same tidal forces compressing it perpendicular to the direction of fall (C). However, there is no mechanism by which the ball would be caused to spin faster and faster (D) simply due to its acceleration toward the black hole. This process is not related to the effects of general relativity on objects falling into a black hole.
