You sir, are incorrect. http://www.colormatters.com/vis_bk_white.html when you look up at the sky at night... do you see WHITE or black? Also in the universe are their BLACK holes or WHITE holes? |

There are two ways to combine colors: additive and subtractive.
A TV works by additive colors: you put a red, green, and blue light and it appears white. A crayon works by subtractive colors. A red crayon absorbs blue and green light. A green crayon absorbs blue and red light. And so on. Put all three together, and any photon hitting the surface will be absorbed by one of the three. We usually define color in terms of what we see (what’s reflected or emitted) rather than what’s absorbed. If you want to say that a red crayon is "really" blue+green, because it’s hoarding all of those blue and green photons... well, I guess that’s one way of looking at it. But it’s really turning those blue and green photons and converting them into heat. They’re not being saved up to be emitted as blue and green later. So we say that "black" is when no photons are reaching your eye, and a "black" surface is one that absorbs all of the photons so that none hit your eye. And space is black because there’s nothing out there putting out photons (except where the stars are). Actually, it’s an important observation that the sky is black. (I’m digressing here.) Scientists call it the Olbers Paradox. If space is infinite, then every point in the sky must eventually point to a star. So why isn’t the sky white? It means that the universe can’t be infinitely big, or infinitely old. The night sky proves that the universe doesn’t go on forever! Space appears black because there are some parts of it from which we can see no light. If you could look directly at the Sun, which is emitting a tremedous amount of light from all colors, you would see a white ball of fire. If you old a white object piece of paper in front of the sun then the paper will appear white because the paper reflects all of the colors, but a black piece of paper would appear black because it absorbs all of the colors. If you take a red crayon and draw on the paper and hold it in the sun light, you will see red. The red crayon absorbs green and blue light, but it reflects red. Green absorbs red and blue. Blue absorbs red and green. If you combine red, green and blue crayons you should have black because all of the colors are absorbed and no light is reflected back at your eye. |

I've never heard of "Olbers Paradox" but it sounds flawed. |

My only concern was this would be a trainwreck instead of some light hearted humor. Good job guys.

Olbers paradox does exist though.

You don't think white cars show dirt and dust?

Mr. Fax is a man, for whom with blacks he has no beef
His drama's with the Mexicans, for he's a taco thief.

You should see the Somalians. Some of the ones that moved into Rochester, MN are so dark they keep getting counted absent at night school.

It's the same as coldness. It an absence of heat. But instead of saying that every time, we have fill in words such as "cold"
