So as far-fetched as it might sound, you could actually go and look for the experimental consequences or the observational consequences to test whether it's true.

So I'm really, really glad you mentioned that because actually that was one of the main points of my book, Dark Matter and the Dinosaurs. One of the reasons I wrote it was because I really think we are abusing the planet. We're changing the planet way too quickly. And just like anything else, when you alter things, it's good to think about the history of what it took to get here.

And as you point out, it took many operations on many different scales. We had to have the formation of structure, the formation of galaxies, the formation of the solar system, the formation of our planet, the formation of humans. I mean, there's so many steps that go into this. And humans, in some part, were the result of the fact that this

Big object hit the earth, made the dinosaurs go extinct, and mammals developed. I mean, it is an incredible story. And yes, something else might come of it, but it won't be us if we mess with it too much.

So you wanted to hear about the shape of things.

So structure formed early on, and now our structure that we live in, so we know about the Milky Way galaxy. So the Milky Way galaxy has the disk you can see in a dry, dark place. That's where stars and light is. But you can also measure, in some ways, the dark matter. And we believe that dark matter is more or less spherically distributed.

And like we said, there's a lot of it, not necessarily in the disk, but just because it's a sphere, there's a lot of it sitting there. And the reason it doesn't collapse, as far as we know, is that it doesn't really, it can't radiate the same way. So because it can radiate, ordinary matter collapses.

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.
