Abstract

In this paper it is shown that the Earth’s rotating speed can be internally measured using the One-way interferometer where the light in one arm of the interferometer travels in an optically dense medium rather than in a vacuum or air. The reason that such a measurement can be made without the null result is the influence of the centripetal force of the Earth’s rotation that is present on the Earth’s surface as in all rotating platforms and that has to be included into considerations. In all the previous analyses of similar experiments the Earth’s rotation was not considered, which leads to various erroneous conclusions. The paper is contrasting the difference between the inclusion of the centripetal force or neglecting it in the analysis of the experiment, which is one of the key points of this paper. The centripetal force compensates for most of the relativistic effects thus allowing the internal motion detection by this type of interferometer. The usual relativistic treatment of this experiment is therefore included as reference for a comparison in this analysis.
