Detailed explanation-1: -The Cosmic Microwave Background (CMB) is the cooled remnant of the first light that could ever travel freely throughout the Universe. This ‘fossil’ radiation, the furthest that any telescope can see, was released soon after the ‘Big Bang’. Scientists consider it as an echo or ‘shockwave’ of the Big Bang.
Detailed explanation-2: -The CMB is markedly uniform, lending support to the theory of cosmic inflation, which posits that the universe expanded much faster than the speed of light just a few tiny fractions of a second after the Big Bang.
Detailed explanation-3: -The accidental discovery of the CMB in 1965 by American radio astronomers Arno Penzias and Robert Wilson was the culmination of work initiated in the 1940s. CMB is landmark evidence of the Big Bang theory for the origin of the universe.
Detailed explanation-4: -This light is called the cosmic microwave background (CMB), and it carries information about the very early universe. Astronomers use the patterns in CMB light to determine the total contents of the universe, understand the origins of galaxies, and look for signs of the very first moments after the Big Bang.
