There is one thing that might explain dark matter
Okay, everyone have the downvote button ready to go? Then begin!
I know many people think it is a scam, and it may be, but I think Brilliant Light Power merits at least a look. I'm no physicist and don't have an opinion about whether Mills' theory is right or not. However, his equipment does produce plasmas, and people with reputations to guard, such as college professors and engineers, have done measurements that show excess heat (i.e., more energy coming out than going in) coming from the reactions Mills' company produces. It's true that they have not produced a WORKING, practical energy source. But neither have fusion pioneers, and we don't go around saying that fusion is crap because of that. Engineering this kind of stuff is hard. How do you contain and extract usable energy from plasma? Don't ask me.
My point here is that Mills postulates that dark matter is actually a form of the hydrogen atom below ground state and that electron orbits can have fractional ground states. He states that the conditions for this to happen don't occur naturally on Earth, although they can in stars. His theory does explain why the sun's corona is hotter than the surface, a fact that's been known for a long time but is difficult to explain using well-understood laws of thermodynamics. It also would explain the observations in this article if, as Mills postulates, dark matter is really sub-ground-state hydrogen atoms (he calls them "hydrinos"). Of course clouds of hydrogen atoms in space are affected by thermal radiation.
I'm also well aware that Mills doesn't believe in quantum mechanics, which I do, but I think the universe may just be more complex and tricky than we understand today. There may be room for hydrinos AND quantum mechanics. I know many physicists reject Mills' work because it doesn't agree with their preconceived notions. And Mills may be wrong, or even a charlatan, but I'd like to see more REAL physicists take a close, unbiased look at what he's doing and study his experiments. Either unmask the fraud and show how he does his tricks, or admit something interesting and possibly VERY beneficial to humankind is going on.
