Suppose an astronaut falling towards a black hole used a watch to check her pulse rate. She notes that her pulse rate remains constant as she falls toward the black hole. (Obviously this astronaut is though.) Why, if clocks run more slowly in strongly curved regions of space-time, does the astronaut find that her pulse rate doesnt change?......
Q. Why does Einstein's theory of relativity imply that gravity is a non-existent force?
A. The theory implies that gravity is a non-existent force that people have invented because we are unable to percieve the curvature of space-time caused by massive objects.
Q. Suppose an astronaut falling towards a black hole used a watch to check her pulse rate. She notes that her pulse rate remains constant as she falls toward the black hole. (Obviously this astronaut is though.) Why, if clocks run more slowly in strongly curved regions of space-time, does the astronaut find that her pulse rate doesn't change?
A. The pulse rate would only appear slower to an observer outside of the Astronaut's frame of reference.
Now we get in to more celestial object related questions in this link below, I couldn't fit everything into my question, so I uploaded the rest in t
I read the printed questions and they all looked good.
But you might mention that the clock on the Sears Tower is moving faster than the one on the lake because it is moving in a longer circumference than the one on the lake (24h diurnal motion.
This might cancel or reverse the answer, I didn't do the math
I didn't have time to download the rest but you seem to have grasped all the points.
You should be doing your own homework, not asking us to do it for you (and if you want to know whether you've got it right you can always hand it in and let your teacher mark it).
been way to long, and much of this we didn't have when i was in school.
Q. What does the concept of conservation of angular momentum have to do with the rapid rotation of neutron stars?
A. Since the size (or distance) of the star shrinks, in order for momentum to be conserved the star would have to spin faster.
(or diameter)???
i'm really not qualified to check many of them, but you seem to be doing well.
A) but do your rocks talk back to you?
B) of course Jesus existed. He may not have been the son of God, but clearly he lived.
