Reality Check
Penultimate Amazing
Note the word "mimicked". I can mimick a galaxy in my bath by rotating water around therefore the galaxy is controlled by the forces in waterPlasma scaling
Plasmas can create very similar structers, from microscopic to galactic size, many plasma experiments have mimiced the shape structure and form of galaxies using the EM forces the plasma contains.
The next step an any simulation is show that it happens in the real world. Where are your observations of galactic-sized plasmoids?
