WebThe cosmic microwave background (CMB) is a whisper of radiation that reaches detectors on Earth from all over the sky. When the CMB was set loose, only 400,000 years after the Big Bang, the universe was very hot and dense and the CMB had the same amount of energy as that produced by a light bulb. Now, nearly 14 billion years later, the universe ... Web1. The Cosmic Microwave Background Radiation. The cosmic microwave background (CMB) radiation is a thermal quasi-uniform black body radiation which peaks at 2.725 K in the microwave regime at 160.2 GHz, corresponding to a 1.9 mm wavelength as in Planck's law.Its discovery is considered a landmark test of the Big Bang cosmology.
