And it's actually because of conservation of angular momentum, it stays a disk and it doesn't just collapse to the center. So our suggestion was that maybe there are some components of dark matter that also radiate. Like I said, that's far from proven. People have looked for disks. They see some evidence of some disks of certain densities. But these are all questions that are worth asking.

Basically, if we can figure it out from existing measurements, why not try?

Well, that's a possibility. We actually don't know what dark matter is in the first place. We don't know what most of it is. We don't know what a fraction is. I mean, it's hard to measure. Why is it hard to measure? For exactly the reason you said earlier, we don't see it. So we want to think of possibilities for what it can be. especially if those give rise to some observational consequences.

I mean, it's a tough game because it's not something that's just there for the taking. You have to think about what it could be and how you might find it.

That would be the way you detect the type of dark matter I've been talking about. People have suggestions for other forms of dark matter. They could be particles called axions. They could be other types of particles. And then there are different ways of detecting it.

I mean, the most popular candidate for dark matter, probably until pretty recently because they haven't found it, is something called WIMPs, weakly interacting massive particles. Particles that have mass about the same as the Higgs boson mass. And it turns out then you would get about the right density of dark matter.

But then people really like that, of course, because it is connected to the standard model, the particles that we know about. And if it's connected to that, we have a better chance of actually seeing it. Fortunately or unfortunately, it's also a better chance that you can rule it out because you can look for it. And so far, no one has found it. We're still looking for it.
