The B-mode polarization of this phenomenon originates from gravitational lensing of E-modes or gravity waves from inflation.
The B-mode polarization of this phenomenon originates from gravitational lensing of E-modes or gravity waves from inflation. The discovery of this phenomenon confirmed the nucleosynthesis model of Alpher, Bethe, and Gamow. It originated during a 300,000-year period called the Dark Ages, and it was discovered by Wilson and Penzias. Seeming to emit from the Surface of Last Scattering, its anisotropy was observed by the COBE ("CO"-"bee"), WMAP ("W"-"map"), and Planck satellites. It appears to echo the Big Bang in a namesake low frequency band. For 10 points, name this ubiquitous 2.7 Kelvin radiation source.
