WIMPS vs. Axions: What is dark matter?
Uh … maybe neither?
First off, there’s a few things that we know about dark matter. Astronomers believe that dark matter is some kind of particle, previously unknown to physics. Whatever it is, it makes up about 80% of the mass of the universe.
Uh … actually, you don't “know” either of those things. You've merely inferred them from observations you don't understand. Just like ancient peoples inferred the existance of gods from observations they didn't understand.
It barely interacts with light, if at all. It barely interacts with normal matter, if at all. It barely interacts with itself, if at all. We also know that it’s “cold”, which means that the individual particles don’t have very high velocities.
Hate to tell you this ... but obviously you know nothing about dark matter. And by the way, NOTHING does all of those things, too.
It basically just sits there and gravitates. But that gravity is essential: it keeps galaxies glued together and provides the scaffolding for the entire large-scale structure of the universe.
Again, you don’t actually “know” any of that. And I doubt *gravity* is what produced the galactic sized, helical wound and rotating, plasma filaments that have been observed to be ubiquitous out there. And THEY appear to comprise the “scaffolding” of the large scale structure of the universe. So … in short … you dark matter gnome believers really don't *know* a thing. You just have belief in gnomes.
Beyond WIMPs and axions, theoretical physicists and cosmologists have come up with all sorts of more complicated possibilities. Maybe the dark matter interacts with itself to some degree. Maybe there are multiple species of dark matter particles. Maybe new forces of physics are involved. Maybe axions can clump together in strange ways. Maybe this, maybe that.
Yeah, and maybe dark matter doesn’t exist at all … and you are simply chasing gnomes. That possibility fits the what you just wrote too. The fact that the gnome believing priests of mainstream astrophysics clearly know so little about dark matter after nearly a century of intense, expensive searches should maybe tell us something. That maybe … just maybe … the gnome believers are idiots who are pulling a scam of monstrous proportions in order to garner power, money and prestige, not understand the universe. Sort of like the leaders of cults do. Think about it. Just saying ...
