Gravitation and Cosmology

Satellite-based test for intermediate-range deviations from Newton's law of gravity. Terrestrial tests of departures from the inverse-square law of gravity have usually foundered as a result of uncontrollable effects from local mass distributions. These effects are eliminated in a satellite-based experiment in which predicted variations from Newton's law would be manifested in a small, but measurable, frequency shift of free-falling oscillators. And Yet It Moves

Effect of gravity and rotational motion on quantum processes. One such process entails the level splitting of atomic states by the rotation of the Earth, with concomitant induction of an optical activity analogous to the Faraday effect. More Than One Mystery

Proposal of a novel solution to the problem of "dark mass" in the universe. The question of what constitutes the nonluminous matter and energy, estimated at over 90% of the content of the universe, is perhaps the single most important unresolved issue of contemporary astrophysics. In a radical departure from standard hot and cold dark matter models, the new theory predicts that a significant component of dark matter comprises very low mass scalar bosons in a Bose-Einstein condensate in the halos of galaxies and throughout the cosmos.
