地球引力场中光速变化的验证
A Test to Verify the Speed Change of Light in the Gravitational Field of the Earth
摘要：
从引力场爱因斯坦方程的Schwarzschild解出发，证明了在球对称的引力场中光速会发生变化，光速各向同性会被破坏.在地球表面，垂直于表面的光速比平行于表面的光速小0.2米/秒。建议用迈克尔逊-莫雷干涉的方法来验证地球引力场中光速的变化和各向同性的破坏。在拟议的实验中，干涉仪的一臂垂直于地球表面，而另一臂平行于地球表面。当两臂转动90度以上时，可直接观察到约0.07干涉条纹的位移。因此，该实验可以看作是广义相对论在球对称引力场中的一个新的验证。如果实验证明引力会改变光速，破坏光速的各向同性，那么这一结果将对基础物理、天体物理和宇宙学产生重大影响。
英文摘要：
Based on the Schwarzschild solution of the Einstein equation of gravitational field, it is proved that the speed of light speed would change and isotropy of light speed would be violated in gravitational field with spherical symmetry. On the surface of the earth, the speed of light vertical to the surface is 0.2m/s less than that parallel to the surface. It is suggested to use the method of the Michelson Morley interference to verify the change of light speed and the violation of isotropy in the gravitational field of the earth. In the proposed experiment, one arm of interferometer is vertical to the earth surface while another is parallel to the surface. When two arms are turned over 90 degree, the shift of about 0.07 interference stripe would be caused which can be observed directly. So this experiment can be considered as a new verification for general relativity in the gravitational field with spherical symmetry. If the experiment shows that gravitation would change the speed of light and violate the isotropy of light speed, the result would cause great effects on foundational physics, astrophysics and cosmolo
