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: -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-3: -The CMB represents the heat leftover from the Big Bang. You can’t see the CMB with your naked eye, but it is everywhere in the universe. It is invisible to humans because it is so cold, just 2.725 degrees above absolute zero (minus 459.67 degrees Fahrenheit, or minus 273.15 degrees Celsius.)

Detailed explanation-4: -According to standard cosmology, the CMB gives a snapshot of the hot early universe at the point in time when the temperature dropped enough to allow electrons and protons to form hydrogen atoms.

Detailed explanation-5: -The cosmic microwave background (CMB) is a faint cosmic background radiation filling all space. Origins: It is thought to be leftover radiation/Heat from the Big Bang, or the time when the universe began. The universe began 13.8 billion years ago, and the CMB dates back to about 400, 000 years after the Big Bang.
