Results of a Tower Gravity Experiment
Abstract
An experimental test is performed for Newton's inverse-square law of gravitation. The test compared gravity values measured on a 600 m tower with upward continued gravity estimates calculated from ground measurements. A significant departure from the inverse-square law was detected, asympotically approaching -500 + or - 35 microsal (1 microsal = .000001 m/sec-sq) at the top of the tower; this indicates that at the base of the tower there is a non- Newtonian attractive force that falls off rapidly with elevation. The results of the experiment are marginally consistent with a one term Yukawa type attractive force but they are fully consistent with two Yukawa type forces, attractive and repulsive, in which case they are also compatible with Airy and Cavendish experiments. The experiment provides evidence that supports the hypothesis of a spin-O graviscalar and of a spin-1 gravi-photon. The masses (approx. = 1 = neV) and coupling constants (not well defined, but at least 3% that of the graviton, and perhaps much more) of both particles are approximately the same, but because m1 > m0, the attractive scalar field is the dominant source of the measured effect.
