Plasma cosmology

Note that I am not an astronomer, and I haven't followed this very closely.At one time, Alfven was given a lot of observation time at Palomar and other observatories, to allow him to find supporting evidence for his plasma theory. Most cosmologists were skeptical.Alfven never did develop solid evidence, and I gather that the astronomers have grown a little tired of it. He probably has more difficulty now in getting telescope time. I think he is viewed as something of a crank.The main criticism I have seen of the theory, is that the plasma should cause some degree of diffusion of the light, and this is not observed.I don't think Alfven's theory is a promising alternative to the Big Bang. If you are a BB skeptic, I suggest you look elsewhere.
