The Spectral Signature of the Micro Background
The spectrum of the cosmic wike wave background is almost a perfect black body, says Dom.

Do you think physics can ever be finished? Ah, depends on what you mean by finished. I do think that we can find the fundamental laws of nature. There's a way the universe works, and we can find it. And maybe we won't - i don't say we will, but i think that they're there.
