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.

Famous quotes containing the words comparison, standard, model, big and/or bang:
“We teach boys to be such men as we are. We do not teach them to aspire to be all they can. We do not give them a training as if we believed in their noble nature. We scarce educate their bodies. We do not train the eye and the hand. We exercise their understandings to the apprehension and comparison of some facts, to a skill in numbers, in words; we aim to make accountants, attorneys, engineers; but not to make able, earnest, great- hearted men.”
—Ralph Waldo Emerson (1803–1882)
“An indirect quotation we can usually expect to rate only as better or worse, more or less faithful, and we cannot even hope for a strict standard of more and less; what is involved is evaluation, relative to special purposes, of an essentially dramatic act.”
—Willard Van Orman Quine (b. 1908)
“I had a wonderful job. I worked for a big model agency in Manhattan.... When I got on the subway to go to work, it was like traveling into another world. Oh, the shops were beautiful, we had Bergdorf’s, Bendel’s, Bonwit’s, DePinna. The women wore hats and gloves. Another world. At home, it was cooking, cleaning, taking care of the kids, going to PTA, Girl Scouts. But when I got into the office, everything was different, I was different.”
—Estelle Shuster (b. c. 1923)
“I do esteem individual liberty above everything. What is a nation for, but to secure the maximum of liberty to every individual? What do you think a nation is?—a big business concern?”
—D.H. (David Herbert)
“Don different from those regal Dons!
With hearts of gold and lungs of bronze,
Who shout and bang and roar and brawl
The Absolute across the hall,”
—Hilaire Belloc (1870–1953)
