Explanation:
Detailed explanation-1: -Because the expanding universe has cooled since this primordial explosion, the background radiation is in the microwave region of the electromagnetic spectrum.
Detailed explanation-2: -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.
Detailed explanation-3: -The CMB doesn’t come from one place; it comes from everywhere. It also doesn’t go in one direction; it goes in every direction.
