Hannes Alfvén from the 1960s to 1980s argued that plasma played an important if not dominant role in the universe because electromagnetic forces are far more important than gravity when acting on interplanetary and interstellar charged particles [REF].
For example, Peratt proposed that the mainstream approach to galactic dynamics which relied on gravitational modeling of stars and gas in galaxies with the addition of dark matter was overlooking a possibly major contribution from plasma physics.
