Is there any possible terrestrial device or process that can empirically prove whether the above conclusions are correct on a minute scale? Cavendish’s torsion bar experiment in 1798, if modified to allow each opposing mass to gravitate freely, should have demonstrated it (Figure 22B).

In the year 2004, we have an even more precise device and process called, “Time of Flight Spectrometry.” It is used in the United States of America F.B.I. crime lab to forensically determine whether the charged ion of an element of matter is present in a substance. Every atomic element has a different atomic weight, so when different atomic elements are accelerated along a tube with a given beam of energy in the laboratory, this device and process measures the time of flight (motion) of each ion in nanoseconds. And it turns out that the lighter the atomic element (ion), the faster its time of flight.[1] Assuming that this device and/or process could be modified to detect the relative speed of small falling bodies with different masses, we should be able to detect whether such small bodies fall toward Earth at slightly different speeds. Why? Because the less the atomic weight of the falling mass, and thus the greater its mass-ratio vis-à-vis the mass of the Earth, the greater should be its Relative Gravitational Acceleration.

In any event, it should now be quite obvious that the apple falls (accelerates) relative to the Earth proportionally faster than the cannonball, the Moon, Jupiter, or the Sun. It should also be obvious that the Earth’s gravity does not “possess the remarkable property of imparting the same acceleration to all bodies,” as Einstein claimed in his General Theory of Relativity.[2]
