Cosmic Latte
November 2nd, 2009
Ever wonder what color the Universe is? Well, wonder no more. Credit goes to Karl Glazebrook & Ivan Baldry for measuring the Average Color of the Universe in 2002. Its hexidecimal RGB code is #FFF8E7 and its name is “Cosmic Latte.”
So why, if the Universe is really that color, do we see a mostly black sky at night? This is something known as Olbers’ Paradox. One solution to the paradox says that not all of the light in the Universe has reached us yet. Another says that because the Universe is expanding, the Doppler effect (as it applies to light/relativity) shifts most of that Universal Light out of our visual spectrum.
