It is known that ME are invariant under the Lorentz transformation, and predict that EM waves travel at the velocity of light regardless of the coordinate system. So, applying instead the Galilean transformation to ME, shouldn't they also predict the same velocity of light as the Lorentz transformation? TY AG* *Yes and that's why Maxwell's Equations needed no modification to be consistent with Special Relativity or General Relativity, although they are inconsistent with Quantum Mechanics. Maxwell's theory predicted what the speed of light would be but it didn't say what specific thing that speed was relative to; before Einstein came along some thought that was a flaw in the theory, but it turned out to be its greatest triumph. * *Does your "Yes" mean that ME will remain invariant under a Galilean transformation (which I doubt), and make the same prediction for the Sol (which I also doubt)?
