The Sun appears to be red as it sets because: 1. Air absorbs red light less than other frequencies (i.e., acts like a red filter). 2. The sunlight has a red shift when you're moving fastest away from it. 3. The Sun cools down to 5000 K each evening. 4. Light is refracted as it enters the atmosphere. 5. The Sun dies in a glorious fireball each evening and is reborn each morning. 6. None of the above.

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.
