Explanation:
Detailed explanation-1: -The discovery of the cosmic microwave background radiation led most astronomers to accept the Big Bang theory.
Detailed explanation-2: -While the CMBR is evidence in support of the Big Bang model, measurements of this radiation have suggested it is very smoothly distributed throughout the Universe. Too smooth for lumpy bits of matter such as stars and galaxies to form.
Detailed explanation-3: -Astronomers have also discovered a cosmic microwave background radiation (CMBR). This comes from all directions in space and has a temperature of about-270 °C. The CMBR is the remains of the thermal energy from the Big Bang, spread thinly across the whole Universe.
