I haven't read the Wiki-article, but I know the paradox in question.
Essentially it goes:
"If the universe is infinite in size, and infinite in age, then not only should we have a perfectly bright and white sky, but we should all be cooked
The paradox is solved by the universe being finite in either size or age.
If the universe is finite in size, then there's only so much light that stars can give out, and not every patch of sky will have stars in it. We have
found this not to be the case - and that, essentially, every portion of the night sky has stars (most just too dim to see).
The other solution is that the universe is finite in age, with stars being born and deing. In this case, some sections will appear empty at least for
We end up with just a few photons from extremely distant stars hitting us instead of the amazing number of photons hitting us from nearby stars, and
the uncountable number of photons hitting us from the sun.
So, why is the sky dark? Photons per area. The photons per area of certain spaces in the night sky are greater than in others - sometimes by a lot
more. Go far, far away from other sources of light - miles and miles away from any city - and you'll start seeing a LOT more stars, as well as the
The further from other light sources you are, the more stars you'll start to see, as less other light gets in the way.
Why, once I was out in a boat on Huron Lake... Marianne Cove it was... not that far from Manitolin Island. It was a September night - cold and windy
as hell. But no moon, no clouds, no interferring light.
The Milky Way, my friends, was WHITE. Not blue, not cloud-ish, but WHITE. It was so bright, that one could see the massive dust-clouds that rimmed it.
The bulge was enourmous, like it would swallow the sky. You truely understand why it was called the Milky Way... and just how MASSIVE it is.
Incredible really. I've never seen it like that before or since.
