    "abstract": "Based on the Schwarzschild solution of the Einstein equation of gravitational\nfield, it is proved that the speed of light speed would change and isotropy of\nlight speed would be violated in gravitational field with spherical symmetry.\nOn the surface of the earth, the speed of light vertical to the surface is\n0.2m/s less than that parallel to the surface. It is suggested to use the\nmethod of the Michelson Morley interference to verify the change of light speed\nand the violation of isotropy in the gravitational field of the earth. In the\nproposed experiment, one arm of interferometer is vertical to the earth surface\nwhile another is parallel to the surface. When two arms are turned over 90\ndegree, the shift of about 0.07 interference stripe would be caused which can\nbe observed directly. So this experiment can be considered as a new\nverification for general relativity in the gravitational field with spherical\nsymmetry. If the experiment shows that gravitation would change the speed of\nlight and violate the isotropy of light speed, the result would cause great\neffects on foundational physics, astrophysics and cosmolo",
