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: -Penzias and Wilson had spotted the CMB, the predicted thermal echo of the universe’s explosive birth. The landmark find put the Big Bang theory on solid ground, suggesting that the cosmos did indeed grow from a tiny seed-a single point-about 13.8 billion years ago.
Detailed explanation-3: -How does Cosmic Microwave Background Radiation provide Evidence that supports the Big Bang? The Big Bang Theory starts with an extremely hot dense object with an extremely small volume that “explodes” and would have radiation that is detectable today in the form of microwaves.
Detailed explanation-4: -The discovery of cosmic microwave background radiation constitutes a major development in modern physical cosmology. In 1964, US physicist Arno Allan Penzias and radio-astronomer Robert Woodrow Wilson discovered the CMB, estimating its temperature as 3.5 K, as they experimented with the Holmdel Horn Antenna.
