Detailed explanation-1: -Because the Universe has been expanding this entire time, the wavelength of that initially hot light has gotten stretched, all the way from gamma rays through visible light and into the microwave portion of the spectrum. This leftover glow from the Big Bang shows up today as the Cosmic Microwave Background, or CMB.
Detailed explanation-2: -The cosmic microwave background radiation (CMBR) that Penzias and Wilson observed is leftover heat radiation from the Big Bang.
Detailed explanation-3: -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-4: -Three key pieces of observational evidence lend support to the Big Bang theory: the measured abundances of elements, the observed expansion of space, and the discovery of the cosmic microwave background (CMB). The CMB refers to the uniform distribution of radiation that pervades the entire universe.
