Chapter 20: Problem 33
Suppose an astronaut falling toward a black hole used a watch to check her pulse rate. She notes that her pulse rate remains constant as she falls closer to the black hole. (Obviously, this astronaut is tough.) Why, if clocks run more slowly in strongly curved regions of spacetime, does the astronaut find that her pulse rate doesn't change?
