In this paper it is shown that the Milky Way Galaxy rotating speed at the location of our Solar system can be measured by using the Michelson interferometer that is built in an optically dense medium rather than in a vacuum or air. The reason that such a measurement can be made is the effect of the centripetal force that is present in rotating platforms and that has to be included into considerations. It is an observational fact that galaxies rotate with an approximately constant orbital speed after a certain distance from the center and this leads to the assumption that some centripetal force contribution must also be present there in addition to the gravitational force of the central compact star. This centripetal force then compensates the relativistic effects thus allowing the motion detection by the interferometer.
