Detailed explanation-1: -The cosmic microwave background (CMB) is leftover radiation from the Big Bang or the time when the universe began.
Detailed explanation-2: -The cosmic microwave background represents the heat radiation left over from the Big Bang. It is the residual heat of creation i.e., the afterglow of the big bang, streaming through space these last 13.8 billion years like the heat radiation from a sun-warmed rock, reradiated at night.
Detailed explanation-3: -The cosmic microwave background (or CMB) fills the entire Universe and is leftover radiation from the Big Bang. When the Universe was born, nearly 14 billion years ago, it was filled with hot plasma of particles (mostly protons, neutrons, and electrons) and photons (light).
