quote:Plasma cosmology is a non-standard cosmology which emphasizes the electromagnetic properties of astrophysical plasmas. Plasma cosmology includes explanations for the evolution of the universe — from the cosmic microwave background, to galaxy formation, to large scale structure. Fundamental to its explanations are interpretations of many astrophysical phenomena by scaling results from laboratory experiments. Advocates for these ideas are mostly ignored by the professional community.A plasma is an electrically-conductive collection of charged particles, possibly together with neutral particles or dust, that exhibits collective behavior and that responds as a whole to electromagnetic forces. The charged particles are usually ions and electrons resulting from heating a gas. The stars and the space between them are made up of plasma. Plasma physics is known to play an important role in many astrophysical phenomena.OverviewThe basic assumptions of plasma cosmology which differ from standard cosmology are:Since the universe is nearly all plasma, electromagnetic forces are equal in importance with gravitation on all scales.An origin in time for the universe is rejected due to causality arguments and rejection of ex nihilo models as a stealth form of creationism. Since every part of the universe we observe is evolving, it assumes that the universe itself is evolving as well, though a scalar expansion as predicted from the FRW metric is not accepted as part of this evolution (see static universe). Plasma cosmology also differs from big bang cosmology methodologically. Its advocates emphasize the links between physical processes observable in laboratories on Earth and those that govern the cosmos. Plasma cosmology is explained as much as possible in terms of the basic behavior of a plasma in the laboratory. Proponents contrast this with the big bang theory which has over the course of its existence required the introduction of such features as inflation, dark matter and dark energy that have not been detectable yet in laboratory experiments.Plasma cosmology was first developed by Swedish physicist Hannes Alfvén together with Oskar Klein, Per Carlqvist and Carl-Gunne Fälthammar beginning in 1962. Alfvén, a recipient of the Nobel Prize in Physics, is well-respected in the scientific community as the founder of modern plasma physics and the inventor of magnetohydrodynamics. While plasma cosmology has never had the support of most astronomers or physicists, a small group of plasma physicists such as Anthony Peratt and Eric Lerner have continued to promote and develop the approach. The level of detail in the development of big bang cosmology is not rivalled by that seen in plasma cosmology, evidenced by the quantity of scientific papers published regarding the two approaches.
