When we look at how stars move in galaxies, they move as if there is a lot of matter there that we can't see.

And she says that this missing matter... It's actually most of the matter in the universe. And it is not visible. And when we say it's not visible, we mean it doesn't interact with light in any way that we've so far detected.

We want it to be something that doesn't interact very strongly with light, if at all. So we want it to be effectively transparent, effectively invisible. And we also want it to be relatively slow moving. So if it's fast moving, then it won't clump together under gravity. It will escape gravity and then you won't form galaxies.

So axions are essentially a class of models that all look kind of similar. So they tend to be lighter in mass. And they also have these very interesting properties that they behave more like a wave than like a particle, depending on the situation you are looking at, the physical scenario you're looking at.

I mean, don't we all? Because it really challenges us to rethink our intuition about what constitutes normal in the universe. Like I always think about in that context, the axion is actually one of these dark matter candidates that challenges us to rethink, oh, it's just a different type of particle.

Because in our head, when we think about particles, we tend to think of them as like maybe little billiard balls bouncing off of each other or something like that. And the axion really requires us to think it's not that because it does behave like a wave in key physical scenarios that are of interest to us for the purposes of dark matter.
