Abstract:

The suggestion in 1986 of a possible fifth force in Nature led to considerable experimental and theoretical effort to detect such a force, and deviations from Newtonian gravity. Geophysical experiments play an important role in the detection of such a force, because the natural scale of geophysical experiment covers a range that is not readily accessible via other methods. This work describes several investigations which search for the presence of non- Newtonian gravity. These include a new tower experiment, and an analysis of exponential models of non-Newtonian gravity. In the course of carrying out the tower experiment problems were encountered in working with the Global Positioning System, and these are described in detail. As a result of this work we can say that support for the validity of Newtonian gravity over geophysical scales has increased. Non-Newtonian Gravity Gravitational Physics.
