Is the cosmic microwave background redshifted

Witrynathe HI 21-cm signal from cosmic dawn. We discuss different phases of cosmic dawn as the ambient gas and the background radiations evolve with the redshift. We address the consequences of several possible heating sources and radiation background on the global 21-cm signal. We further review our present perspective of WitrynaThe apparent expansion of the universe, inferred from redshifted spectra of distant galaxies; The fact that the Big Bang can account for the observed relative abundances of hydrogen and helium; The observed cosmic microwave background (CMB) radiation, thought to be an “afterglow” from a time about 400,000 years after the supposed Big …

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.

And it's this in combination-- so it's this data that we're getting, this observation, in combination with the fact that the further we look out to galaxies and clusters of galaxies, they all seem to be moving away from us. They're all red shifted.
