Not ignoring your latest questions/comments; I'm still a few steps further back.
If gravity does not travel how does it act at distance and how can we even do the experiments to measure its speed?
Wikipedia says: “…the speed of gravity is the speed at which changes in a gravitational field propagate. This is the speed at which a change in the distribution of energy and momentum of matter results in subsequent alteration, at a distance, of the gravitational field which it produces.”
“For static fields, such as …… the gravitational field connected to a massive object, the field extends to infinity, and does not propagate.”
Would it not follow from this that gravity is a static field, and that what is being measured is changes within a gravitational field, rather than any intrinsic motion of the field itself?
