Detailed explanation-1: -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.
Detailed explanation-2: -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-3: -Why does the Big Bang theory predict that the cosmic background radiation should have a perfect thermal radiation spectrum? A) The background radiation came from the heat of the universe, with a peak corresponding to the temperature of the universe.
