Hypothetical Universe Thought Experiment?
Suppose in a hypothetical universe, the only matter present consists of two planets, one of which is spinning relative to the other, on an axis which joins the centers of the two planets. There is a man standing on the equator of each planet. Which man feels the centrifugal force? [By 'planet' here I am not implying a satellite, just a spherical body]
Is the answer different if these planets are in a deserted region of the present Universe?

Here's the problem with that. If one is spinning relative to another then the other is spinning relative to the other from both reference frames. However, viewing the planets from space would tell you which one is actually rotating. So, the man who is on the planet that is actually moving will feel the centrifugal force. This is why general relativity was formulated; to create a universal reference frame.

No, the heart beat travels alongside the cable on the fee of sound. velocity of sound travels at 700mph in air yet quicker via solids, in case you detect a mile of railway music and hit one end with a hammer, the "bong" will come out of the different end some seconds later. an identical happens with a tug on a rope, all ropes are elastic (stretchy) even kevlar.

My guess is that both of them would feel it, but the strength of the effect would be reduced.
