Abstract :
A non-Big-Bang plasma model is used to predict the submillimeter spectrum of the cosmic background radiation (CBR). Early intermediate-mass stars heat dust which, in turn, warms electrons trapped in force-free filaments emitted by galactic nuclei. Current stars contribute further heating by the same synchrotron mechanism. The electrons emit a nonblackbody radiation which matches the observed CBR spectrum and isotropy. The model also predicts intergalactic absorption of radio radiation, as confirmed by observations of spiral galaxies, and accurately predicts the spectrum of radio-quiet sources
