Original sentence: A tenative list of such properties include scaleability, Birkeland currents (electric currents), double layers (charge separation), filamentation, plasma instabilities, and current circuits.Plasma cosmology as a cosmological model is outside the mainstream of academic cosmology.While the Big Bang model of cosmology suggests that the early universe was composed entirely of plasma from reheating until recombination, plasma cosmology proposes that many cosmological processes that are explained through gravitational physics in Big Bang cosmology are in fact electromagnetic in nature
Edited sentence: It is usually a position beyond mainstream cosmology and usually not taught in  academic situations.Plasma cosmology, however, proposes that many other cosmological processes are explained through the standard properties of plasmas, such as scaleability, Birkeland currents (electric currents), double layers (charge separation), filamentation, plasma instabilities, and current circuits
