Said
"Start every day off with a smile and get it over with."
~W.C. Fields
"Of all the preposterous assumptions of humanity over humanity, nothing exceeds most of the criticisms made on the habits of the poor by the well-housed, well-warmed, and well-fed."
~Herman Melville

Color of the Universe
As readers can probably guess by looking at the logo bar on this page, I like colors and spectra. So I loved reading about the color of the universe:According to Karl Glazebrook & Ivan Baldry, astronomers at Johns Hopkins University, the universe is green. Sooner or later (like in a few billion years), the universe will be red. This is their chart, which shows the color of the universe (the left and right colors are for comparison):
Lest you think the search for the color of the universe was a quest for new and improved paint colors, researchers say, "The cosmic spectrum tells us about the history of star-formation in the Universe." The decimal RGB equivalents are 0.269, 0.388, 0.342.
Glazebrook and Baldry used John Walker's "Colour Rendering of Spectra" work to figure out the RGB equivalents.
I think the universe was a much prettier color about six billion years ago.
