<p>Create/expand category description</p> <p><b>New page</b></p><div>This category collects work in &#039;&#039;&#039;plasma cosmology&#039;&#039;&#039; — the programme, descending from Hannes Alfvén, that treats electromagnetic forces in cosmic plasma as the dominant organizing influence in the universe, in place of gravity alone.<br /> <br /> Its claims are that the universe is filled with plasma threaded by &#039;&#039;&#039;Birkeland currents&#039;&#039;&#039; and magnetic fields; that these currents form filaments which pinch under the z-pinch effect to produce stars and galaxies; that galactic rotation curves and structure may follow from electromagnetic rather than gravitational dynamics, removing the need for dark matter; and that laboratory plasma experiments scale predictably to cosmic dimensions, making the field testable in a way that a gravity-only cosmology is not.<br /> <br /> Alfvén, who received the 1970 Nobel Prize for magnetohydrodynamics, argued that cosmology had gone wrong by extrapolating from mathematics rather than from plasma laboratory practice.
