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..
Cosmic background radiation is electromagnetic radiation that fills all space.
The origin of this radiation depends on the region of the spectrum that is observed.
One component is the cosmic microwave background..
The CBR is a nearly uniform radiation received from all regions of the sky.
The evidence is apparent as a radio signal with a temperature of 2.
Cosmic background radiation (usually abbreviated CMB, but also CBR, and sometimes called relic radiation) is a long wavelength type of electromagnetic radiation that is believed by cosmologists to show evidence of left over energy from the big bang, a theory for the possible explosion that began the universe..
In 1965 it was discovered that low energy microwave radiation (at 7.35 cm uncorrected) reaches us from all directions in space (about 400 photons cm−3).
This is referred to as the cosmic background radiation whose wavelength corresponds to radiation from a black body of temperature 2.
The Big Bang and Cosmic Microwave Background – October 2006 Copeland, Ed. "CMBR:
CMB is landmark evidence of the Big Bang theory for the origin of the universe.
In the Big Bang cosmological models, during the earliest periods, the universe was filled with an opaque fog of dense, hot plasma of sub-atomic particles.
