Detection of dark matter and tests of the weak equivalence principle

J. W. Moffat

Open publisher page 3 citations

Abstract

Estimates of the predicted magnitude of deviations from Newtonian gravitation and the possible violations of the weak equivalence principle in the nonsymmetric gravitational theory (NGT), caused by cosmions in the earth, are given. An E\"otv\"os or free-fall Galileo experiment on the Earth's surface or in space with $\frac{\ensuremath{\Delta}a}{g}\ensuremath{\le}{10}^{\ensuremath{-}12}$ could test NGT and confirm the existence of dark matter.
