I am quite amazed that noone has pointed out that in terms of the cosmic microwave background, the sky is not black. The radiation that travels the furthest before hitting us is this background radiation. It only appears to be dim because it has been redshifted a huge amount due to the expansion of the universe since then.

But yes - everywhere you look in the sky (unless there is something in the way), you are looking directly at the intense fire of the birth of our universe. Red-shifted until you can't even see it any more.
