Hi I am new to this forum and I am not even studying physics nor currently taking any classes in my old age. But I had a thought last night whilst tossing in my sleep and the question arose to my mind about what it would be like if I went to the North Pole and stood dead center aligned exactly standing on the earth's physical pivoting axis point? If at night I stood there looking up at the stars I would guess that I would just see them spinning in a circle directly above me (imagine a line drawn staight through and connecting the earths north and south poles axis). I know standing on the street in say NYC and looking up at the starts I watch the pattern as how the stars move across the sky. The centrifigual forces acting upon me (us) in NYC are not the same I would guess as if I were standing directly on the north or south poles pivot axis right? Would that change the physical behavour or properties of things as we normally know or feel them in the middle of the earths (like standing at the equator where the velocity of us spinning through the air space is much greater than the same person standing exactly on the earths's north pole rotating axis)? Hope you get the jist of my question here. Makes me wonder. (like a spinning phonograph record spinning at 33RPM, the velocity of the outer grooves are traveling at a much higher rate of speed than the inner grooves of same record. But the entire record can be said to all be spinning at the same speed. Different parts of that record platter are using up and exhibiting different energy levels or physical properties). Just wondering. Do the laws of physics say explaning gravity or other properties change or get modified at the earth's axis vs at the equator spinning (energy levels obviously are different to be rotating at the same rate but at different velocities. Also just thinking about another question that arises based on what I've heard about traveling at high speeds (like Einstein's theory if an astronaut took off into space at the speed of light and came back a year later, he would have aged one year but the everyone on earth would have aged many more years). So if speed slows down time and therefore aging, do we live longer if we are located by the equator (where rotational speed is moving us much faster through space) than if we were up at the north pole axis pivot turning at a turtles pace? Thanks!
