I've been kind of wondering if intergaltic space is pitch black. The reoson the sky glows is caused by sublinal stars and the zodiacal light. If you were to leave the <br />disk of the solar system you would be treated to a sky twice as black as that visible on earth. My question, is if you were to leave the milky way would you be treated to a sky of complete pitch blackness. I would think so. I<br /> mean there is nothing out there really to glow right?<br />I'm mean even the radiation left from the big bang wouldn't brighten the sky anything away from almost complete darkness. When you are out in the woods in overcast or a deep fog the surroundings are at 300 K and yet it looks completly black. The universe is only 3 K or so. You might say that the light galaxies have been giving off has kind poluted the universe with a diffuse light, but as "soon" as it hits a cold galixy it will<br />start to be transfered out of the visible. Thats why things like spitzer work so well.
