Cosmic microwave background radiation
In
cosmology, the cosmic microwave background radiation (most often abbreviated CMB but occasionally CMBR, CBR or MBR, also referred to as relic radiation) is a form of
electromagnetic radiation discovered in 1965 that fills the entire universe . It has a thermal 2.725
kelvin black body spectrum which peaks in the
microwave range at a frequency of 160.2
GHz, corresponding to a wavelength of 1.9 mm. Most cosmologists consider this radiation to be the best evidence for the
Big Bang model of the universe.
