Tired light models invoke a gradual energy loss by photons as they travel through the cosmos to produce the redshift-distance law. ... The tired light model can not produce a blackbody spectrum for the Cosmic Microwave Background without some incredible coincidences. ... So the CMB must have come from a far away part of the Universe, and its photons will thus lose energy by the tired light effect. ... Assume that the CMB starts out as a T = (1+z)*T_o = 2.998 K blackbody, which is the blue curve. ...
