A Black body the way we know is black only because its temperature is our ambient temperature. If you start heating it up it will turn dark red, orange, yellow...blue, Xray - think of molten lava or steel and sun, what color would sun be if cooled down to room temparture? No practical way to find out, thank God. "Black" in "black" radiation just specifies what kind of spectrum to expect: it is the continuum without any specific peaks or valleys (aka colours), with a maximum value (aka prevalent color) at some wave-length that depends on the temperature of the body (Josef Stefan's law). The theoretical determination of the "black body" spectrum by Max Planck was the first big step in the direction of quantum physics. Re radiating back into space - during ice ages, the earth was more white than green, so it reflected even more and in a way "fought" against warming up. And now that the earth is darker(even at 30.000 ft over the oceans, one can see a grey layer of soot & Co), it takes up more (a tiny, but significant amount) than a couple of hundred years ago. So what's the solution? a) I never said there's a problem, did I ;? and b) turn on the air condition, for Chrissake ; dj
