Interesting article on how it is possible to indirectly detect the effects of the Cosmic Neutrino Background and (of course) how it is consistent with the Big Bang model.

If this were true, there would be an early signal left over from when the Universe was just one second old: neutrinos and antineutrinos. Known as the cosmic neutrino background (CNB), it was theorized generations ago, but was dismissed as undetectable. Until now. A very clever team of scientists has just found a way to see it. The data is in, and the results are incontrovertible: the cosmic neutrino background is real, and agrees with the Big Bang.

Very interesting reading. Thanks Strange.
