The cosmic microwave background (CMB, CMBR) is electromagnetic radiation that fills all space in the observable universe. It is the cooled remnant of the first light that could travel freely through the universe, dating back to about 380,000 years after the Big Bang. This faint background glow is almost completely uniform and represents a crucial piece of evidence supporting the Big Bang model of cosmology.
