This is impressively inaccurate: plasmas (charged and magnetic fluids) are basically the entirety of stellar evolution and the main part of everything up to galaxy evolution, so we have pretty good limits on the magnetic fields out in the universe.
There is also direct measurements of magnetic fields integrated along the line of sight out to cosmological distances, and of course every spectra ever taken has measured the ionization level of the luminous gas.
- oldandtired 8y agoI agree. Yet the models assume that gravity is the only influence for the motion of the galaxies, etc. We can see evidence of other phenomena but.... I have had this discussion with trained working physicists and the general reaction has been that these phenomena are completely insignificant in relation to stellar, interstellar, galactic and intergalactic motion. So where do we stand? If the orders of magnitude difference in strength between electric and magnetic fields and the strength of gravity is over 35. What kinds of effects do we expect with these kinds of differences? Especially when we are looking at plasmas and all sorts of ionisation. I don't know, but it does lead to intriguing questions.
