Detailed explanation-1: -The radiation from the CMB in photons (particles representing quantums of light, or other radiation) was scattered off the electrons. “Thus, photons wandered through the early universe, just as optical light wanders through a dense fog, ‘’ NASA wrote.
Detailed explanation-2: -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-3: -However, they have been cosmological redshifted to longer wavelengths during their 13 billion year journey through the expanding Universe, and are now detected in the microwave region of the electromagnetic spectrum at an average temperature of 2.725 Kelvin. This agrees well with what Big Bang theory predicts.
