Intergalactic radio absorption and the cobe data

The COBE data on cosmic Background radiation (CBR) isotropy and spectrum are generally considered to be explicable only in the context of the Big Bang theory and to be confirmation of that theory. However, this data can also be explained by an alternative, non-Big Bang model which hypothesizes an intergalactic radio-absorbing and scattering medium. A simple, inhomogenous model of such an absorbing medium can reproduce both the isotropy and spectrum of the CBR within the limits observed by COBE, and in fact gives a better to fit to the spectrum observations than does a pure blackbody. Such a model does not contradict any other observations, such as the existence of distant radio sources.
