Detailed explanation-1: -The cosmic microwave background radiation is the faint remnant glow of the big bang. This false color image, covering about 2.5 percent of the sky, shows fluctuations in the ionized gas that later condensed to make superclusters of galaxies.
Detailed explanation-2: -The cosmic microwave background (CMB) is leftover radiation from the Big Bang or the time when the universe began.
Detailed explanation-3: -The cosmic microwave background (or CMB) fills the entire Universe and is leftover radiation from the Big Bang.
Detailed explanation-4: -However, the Big Bang’s leftover glow will never disappear entirely. No matter how far we extrapolate into the future, even as the density of photons and the energy-per-photon both continue to drop, a large enough, sensitive enough detector tuned to the right wavelength could always identify it.
