WebGeneral acceptance soon followed of its interpretation in inflation cosmology as the CMB radiation left over from the primeval universe. The redshifts of observed galaxies and astronomical bodies suggested that the universe was expanding, but the Big Bang model could not be confirmed until the discovery of the CMB.
