If so, I would expect things located at the equator would be lighter (more centrifugal force) than those same thing located at either pole (less centrifugal force). I’m not a physicist (obviously) but this just seems to make common sense to me. Common sense, of course, is often wrong.

I have loved the wrap up, my eyes are open to something.
