When the dark matter/dark energy theories first started coming around, my first thought was, "That sounds like a fudge." The universe was not behaving the way theory predicts - the rotation rates of the galaxies did not go the way that gravity predicted. So, dark matter was proposed to create more mass where none could be seen, to restore balance to the universe. The add-ons continued, to the point where astrophysics now suggests that an overwhelming percentage of the physical universe is invisible and indetectable. Which sounded strange, but I let it pass having other things to occupy my mind, and three kids to boot.
I ran across the plasma cosmology through sf author James Hogan, and I read a little more, and it does explain some things that conventional theories do not, and often, it does so much more simply. In the case of the rotation of spiral arms, it suggests that electrical currents are affecting the rotation speed - without recourse to invisible matter. Electromagnetism is 40 or so orders of magnitude stronger than gravity, so, hey, that might make a difference, seeing as 99% of the visible universe is plasma. In the case of the sun, if these electrical currents are out there in the galaxy, then it suggests that we are in the middle of them too, and like the above post suggests, the solar wind does pretty much meet the definition of an electrical current.
The anonymous coward's tone is a little abrasive, but modding him down for espousing a non-mainstream viewpoint is not cool, imho. There's some interesting thinking going on. And won't we all be embarrassed if, a hundred years from now, the hip people look on our astrophysics with dark matter and dark energy as a more recent version of epicycles?
