I didn't know, did you?

Cool.

Well sure, if you just mix the light sources then that's what you would get. But I'd think the "color of the universe" (not just it's stars) is actually a shade very close to black.

But it's the large numbers of old red stars and young blue stars in the universe that gives us the green

Do we have documentation on the age of these stars?

yup black

Well really, from that point of view, the universe would be colorless, as there's nothing in space for light to reflect off of (hence black, or nothing). :P

But colorless is black. Black is not really even a color. White light is the entire spectrum of colors combined...and black is simply the absence of any color...or even more simply, nothing.

Right?

[OuTpaTienT]

hmmm, thinking about it even more (way too much) just because something is black doesn't mean it's nothing. What about black holes? They have massive amounts of matter. Certainly not nothing...yet they are black as black gets.

[Bullion]

thats only because light cannot escape a black hole, that they appear to black., and then when you think about it this is only subjective to humans, who only see our spectrum, imagaine a super alien who could see all frequencies..... hehehe

crazy talk off the road

Well, my certain definition, black is the absense of color, like you said. Therefor black holes would be colorless. Visibly colorless anyway, they give off gamma rays or something. :P It all depends on how you define something as having color and black itself. :P
