Physicists have some ideas about where mass comes from...Having "some ideas" and "knowing" are two different things.
Are the physicists not figuring this stuff out quickly enough to suit you? Maybe you should threaten to pull their funding...that might get 'em moving towards turning their mere ideas into real knowledge!
"Serenity now!"
The trouble with Plasma Cosmology is the same thing that all cosmologies other than the BB suffer from: they don't predict observed phenomona, such as elemental abundances, or the isotropic Cosmic Microwave Background Radiation, or the observed small anisotropies in the CMBR.
The BB cosmology, especially the Inflationary varient, handles all of them beautifully.
