Evidence for the Big Bang Theory for the beginning of our universe which is seen by astronomers studying the light which is coming to us from far away quasars and galaxies is that the light is shifted towards the ____________ end of the spectrum in all of those celestial bodies (except the galaxy of Andromeda). This is indicative that those celestial bodies are all (but Andromeda) moving away from us (our point in space). Group of answer choices red green orange ultraviolet blue

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.
