    The Fizeau Experiment
    Fizeau measured the speed of light in moving mediums, most notably moving water. Fresnel proposed a "drag coefficient" which putatively described how strongly a moving material medium "dragged" the ether. SR predicts no ether but does predict that the speed of light in a moving medium differs from the speed in the medium at rest, by an amount consistent (to within experimental resolutions) with these experiments and with the Fresnel drag coefficient.
    according to this, light speed is different in a moving medium,
    and i think its is relative to the theory of "frame dragging", if
    that is correct what is the medium that is in motion?
