Explanation:
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: -CMBR is a second piece of evidence to show the expansion of space, and this supports the Big Bang model of the origin of the Universe. The short wavelengths of the gamma radiation emitted in the initial explosion are believed to have become stretched due to the expansion of space into longer wavelength microwaves.
