Explain Alfvén's concept of the plasma universe.
The 'plasma universe' is my view that electromagnetic forces, mediated by plasmas, are far more significant in shaping the cosmos than gravity alone, which is the prevailing dogma in much of astrophysics. I observed how plasmas behave in the laboratory – forming complex structures like double layers, magnetic ropes, and filaments driven by electric currents. These same phenomena, I argue, are writ large across the universe. Galaxies, for instance, are not merely collections of stars pulled together by gravity, but are organized by vast electrical currents and magnetic fields within cosmic plasmas. The universe is, in essence, a giant plasma laboratory, and we must interpret its features through this empirical understanding.
