Today, you are a member of… Mach 10

Are expanding orbits widening gyres where the falcon gets deaf to falconers or one of many circles marked by a blackbird flying out of sight? This here week, in the red-shifting universe, it’s time to understand, dear Members, that it is not all about you in that classical mechanics way of absolute space and centrifugal force. It may just be that rotation is very much relative and indeed a fictictious force that, although hard to deny, does not prefer this object over that object necessarily. So whether you’re revolving around the sun or in fact spinning around a minor planetoid, know that the math is what you make of it and inertia originates in a kind of interaction between bodies.
