Possible test of the strong principle of equivalence.
Abstract
It is suggested that redshift determinations of X-ray and gamma-ray lines produced near the surface of neutron stars which arise from different physical processes could provide a significant test of the strong principle of equivalence for strong gravitational fields. As a complement to both the high-precision weak-field solar-system experiments and the cosmological time-variation searches, such observations could further test the hypothesis that physics is locally the same at all times and in all places.
