Probing the anisotropic velocity of light in a gravitational field: another test of general relativity
arXiv:gr-qc/9912014
Abstract
A corollary of general relativity that the average velocity of light between two points in a gravitational field is anisotropic has been overlooked. It is shown that this anisotropy can be probed by an experiment which constitutes another test of general relativity.
