Yes, and I repeat in retrospect. all my comments were regarding the g force never the potential. That is why I emphasize, that even in my mistakenly inverted negative Y diagrams ( springs pulled down rather than compressed ), I intended to express the g force. You can do better than that. In post #579 I assumed to measure the g forces sum over shell surfaces at different radii, pretending we are talking of radiation-like gravitons (hopefully mass-less). There might not be a unit for that measurement, but as an example, the total energy emitted by the sun measured at any distance, on any shell it encloses, remain constant (absorption ignored). some with the g force., field. just because the force or radiation acts over a greater area, and measures proportionally weaker, does not mean the total has diminished with distance. It that is a trivial truth, then there is more g force outside the surface then the interior, simply because the exterior goes on to infinity. ( the area below the red line). If off topic reply is allowed? born 1930, and had a great time skateboarding today, respectfully maintaining the balance of the g force and velocity--- teaming up with my 8 year old daughter. There is no fool like an old fool.
