Comparison To The Standard Model of Big Bang Cosmology
Proponents of plasma cosmology claim electrodynamics is as important as gravity in explaining the structure of the universe, and speculate that it provides an alternative explanation for the evolution of galaxies and the initial collapse of interstellar clouds. In particular plasma cosmology is claimed to provide an alternative explanation for the flat rotation curves of spiral galaxies and to do away with the need for dark matter in galaxies and with the need for supermassive black holes in galaxy centres to power quasars and active galactic nuclei. This is controversial, as theoretical analysis shows that "many scenarios for the generation of seed magnetic fields, which rely on the survival and sustainability of currents at early times ", i.e. Birkeland currents of the magnitude needed (say 1018 Amps) for galaxy formation are not thought to exist.
Light element production without Big Bang nucleosynthesis (as required in e.g. Alfvén-Klein cosmology) has been discussed in the mainstream literature and was determined to produce excessive x-rays and gamma rays beyond that observed. This issue has not been completely addressed by plasma cosmology proponents in their proposals.
In 1995 Eric Lerner published the only proposal based on plasma cosmology to explain the cosmic microwave background radiation (CMB) since the Cosmic Background Explorer (COBE) results were announced in 1992. He argues that his model can explain both the fidelity of the CMB spectrum to that of a black body and the low level of anisotropies found. The sensitivity and resolution of the measurement of the CMB anisotropies was greatly advanced by WMAP. The fact that the CMB is so isotropic, in line with the predictions of the Big Bang model, was subsequently heralded as a major confirmation of the Big Bang model to the detriment of alternatives. These measurements show the acoustic peaks in the early universe are fit with high accuracy by the predictions of the Big Bang model. There has never been an attempt to explain the detailed spectrum of the anisotropies within the framework of plasma cosmology.

“In comparison to the French Revolution, the American Revolution has come to seem a parochial and rather dull event. This, despite the fact that the American Revolution was successful—realizing the purposes of the revolutionaries and establishing a durable political regime—while the French Revolution was a resounding failure, devouring its own children and leading to an imperial despotism, followed by an eventual restoration of the monarchy.”
—Irving Kristol (b. 1920)
“But the best read naturalist who lends an entire and devout attention to truth, will see that there remains much to learn of his relation to the world, and that it is not to be learned by any addition or subtraction or other comparison of known quantities, but is arrived at by untaught sallies of the spirit, by a continual self-recovery, and by entire humility.”
—Ralph Waldo Emerson (1803–1882)
“Error is a supposition that pleasure and pain, that intelligence, substance, life, are existent in matter. Error is neither Mind nor one of Mind’s faculties. Error is the contradiction of Truth. Error is a belief without understanding. Error is unreal because untrue. It is that which seemeth to be and is not. If error were true, its truth would be error, and we should have a self-evident absurdity—namely, erroneous truth. Thus we should continue to lose the standard of Truth.”
—Mary Baker Eddy (1821–1910)
“There are very many characteristics which go into making a model civil servant. Prominent among them are probity, industry, good sense, good habits, good temper, patience, order, courtesy, tact, self-reliance, many deference to superior officers, and many consideration for inferiors.”
—Chester A. Arthur (1829–1886)
“... there is ... a big aspect of play in writing novels, and making the story more and more elaborate is just more and more fun.”
—Gish Jen (b. 1956)
“This is the way the world ends
This is the way the world ends
This is the way the world ends
Not with a bang but a whimper.”
