Redshift microwave background radiation

WebRed-shift data provides evidence that the Universe, including space itself, is expanding. Evidence from CMBR Astronomers have also discovered a cosmic microwave … The cosmic microwave background radiation and the cosmological redshift-distance relation are together regarded as the best available evidence for the Big Bang event. Measurements of the CMB have made the inflationary Big Bang model the Standard Cosmological Model. The discovery of the CMB in the mid-1960s curtailed interest in alternatives such as the steady state theory.
