I certainly share your doubts, Bill; I was simply making the point that, according to SR, we cannot know if we are moving, unless we are accelerating; and I was wondering what, if any, influence that might have on the point Finiter was making.

The present view is that we cannot distinguish whether we are moving or not. So the fact may be either 'we are moving' or 'we are not moving'. Both the answers are equally logical, and so we can chose one. I opt for the former, ie, we are moving. (as stated earlier, I propose that energy is the quality of matter and so no body can remain at rest).

Going further in that direction, I would say that it is possible to know whether we are moving (without any reference point that remains at rest). What I propose is a G that depends upon speed, ie, G is directly proportional to square of the speed. When a mass like Earth is at rest the measured value of G would be zero.
