CONFIRMED: The Big Bang’s Last Great Prediction!

“There’s also a very, very subtle effect: neutrinos, which only make up a few percent of the energy density at these early times, can subtly shift the phases of these peaks and troughs. This phase shift — if detectable — would provide not only strong evidence of the existence of the cosmic neutrino background, but would allow us to measure its temperature, putting the Big Bang to the test in a brand new way.”

A new technique taking advantage of data from the Planck satellite has just detected the cosmic neutrino background definitively and in a new way, with the subsequent polarization spectra — set to be released by the Planck team — ready to confirm the greatest prediction of all: the cosmic neutrino background’s temperature!
