A.A. Michelson and E.W.Morley in 1881 measured the speed of light in the
direction of the Earth and the speed of light at right angles to the
Earth`s motion. No difference was found.

Light does have different speeds in different media. This causes light
to bend when passing from one medium to another. The "speed of light" is
through space or a vacuum. The more a substance bends light, the higher
its refractive index.

I said Einstein may be wrong. I should have added that I don`t think so.
