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..

It began as a branch of theoretical physics through Einstein's 1917 static model of the universe (Einstein 1917) and was developed in its early days particularly through the work of Lemaître (1927).
As recently as 1960, cosmology was widely regarded as a branch of philosophy.Sep 26, 2017.
cosmic background radiation.
Weak radio-frequency radiation traveling through outer space with equal intensity in every direction.
It is thought to be residual radiation from a period shortly following the big bang, when the universe was very hot.
Also called microwave background..
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..
In the Big Bang model for the formation of the universe, inflationary cosmology predicts that after about 10 −37 seconds the nascent universe underwent exponential growth that smoothed out nearly all irregularities.
The remaining irregularities were caused by quantum fluctuations in the inflaton field that caused the inflation event.
The cosmic microwave background ( CMB, CMBR) is microwave radiation that fills all space in the observable universe.
It is a remnant that provides an important source of data on the primordial universe. With a standard optical telescope, the background space between stars and galaxies is almost completely dark.
The "Big Bang" scenario, with cosmic inflation and standard particle physics, is the only cosmological model consistent with the observed continuing expansion of space, the observed distribution of lighter elements in the universe(hydrogen, helium, and lithium), and the spatial texture of minute irregularities (anisotropies) in the CMB radiation.
The standard model of cosmology rests on the assumption that, on very large scales, the Universe is homogeneous and isotropic, meaning that its properties are very similar at every point and that there are no preferential directions in space.
