  The quest for a complete theory of microphysics is probably near the top of
the agenda in fundamental physics today. We survey existing modifications of
quantum mechanics to assess their potential. In the following we present recent
results in microdynamics, focussing on dynamic charge. The theoretical model,
valid at all length scales, relates mass oscillations to static electric and
gravity fields. The same concept is used, with substantially lower frequencies,
to compute the intensity of gravity waves within the solar system. These waves,
in the range of kilohertz, can in principle be detected.
