Fifth Force

Many theories which unify gravity with the other known forces of nature predict the existence of an intermediate-range "fifth force" similar to gravity. Such a force could be manifest as a deviation from the gravitational inverse-square law. Currently, at distances near 10-1 m, the inverse-square law is known to be correct to about one part per thousand. I present the design of an experiment that will improve this limit by two orders of magnitude. This is accomplished by constructing a torsion pendulum and source mass apparatus that are particularly insensitive to Newtonian gravity and, simultaneously, maximally sensitive to violations of the same.

Fifth Force

The mechanism of a decaying cosmological constant in terms of a scalar field has been criticized for its ensuing diminishment of the gravitational constant with time. Contrary to a naive view, however, the physical results can be made fully nontrivial, as demonstrated explicitly by a simple model in which the scalar field generates particle masses that increase with time, but in such a way that the gravitational constant stays constant asymptotically when time is measured by an atomic clock. The scalar field might also be an origin of the fifth force.
