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: -Because the expanding universe has cooled since this primordial explosion, the background radiation is in the microwave region of the electromagnetic spectrum.
Detailed explanation-3: -The first-year WMAP results put the time at which P(t) has a maximum as 372, 000 years. This is often taken as the “time” at which the CMB formed.
Detailed explanation-4: -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.
