Speed of light

The speed at which the light travels in a vacuum is unbiased for both the source and inertial frame of reference of the observer. This was postulated by the physicist, Albert Einstein, by observing the theory of electromagnetism of Maxwell. Also, there was no evidence for the luminiferous aether, that is, the medium for the propagation of light where the electromagnetic field exists.
