Orbits in the case of the inverse cube law of force are virtual rather than real. The motion of atoms in a solid structure is that of a vibration in a straight line about a fixed point. The decay times of unstable units are velocity dependent. The variation of force with velocity requires that these particles be subject to no internal disruptive force as long as the velocity of light can be maintained. The interpretation of the effect as a variation in time is most unfortunate.
Measurement is able to provide a number, but fails to reveal any interpretation.
Interpretation depends on theory which may not exist at the time of the experiment. The general procedure of science is that of experimentation followed by the development of theory to fit the results. In every case, the preconceived notion, which is the bane of all science and the basic point of human failure, taints every interpretation. Thus we find that the interpretation of the Pound-Rebka experiment, the Ives experiment, the measured mass increase in the electron, and all measurements by means of the atomic clock are biased in favor of relativity simply because that theory was already in existence. The most difficult thing that can be imagined in the field of science is that of being able to eliminate the preconceived notion.
