Detailed explanation-1: -The Cosmic Microwave Background radiation, or CMB for short, is a faint glow of light that fills the universe, falling on Earth from every direction with nearly uniform intensity.

Detailed explanation-2: -The cosmic microwave background (CMB) is leftover radiation from the Big Bang or the time when the universe began. As the theory goes, when the universe was born it underwent rapid inflation, expansion and cooling.

Detailed explanation-3: -The cosmic microwave background (or CMB) fills the entire Universe and is leftover radiation from the Big Bang.

Detailed explanation-4: -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-5: -This is called the 3 Degree Kelvin Background Radiation, or the Cosmic Background Radiation, or the Microwave Background. These names come about because this radiation is essentially a black body with temperature slightly less than 3 degrees Kelvin (about 2.76 K), which peaks in the microwave portion of the spectrum.
