#403 – Lisa Randall: Dark Matter, Theoretical Physics, and Extinction Events

That's absolutely true. And it's certainly writing books. I realized also how many of our words are based on how we see the world. And that's true. And that's actually one of the fantastic things about physics is that it teaches you how to go beyond your immediate intuition to develop intuitions that apply at different distances, different scales, different ways of thinking about things.

I just did, I think. I made it to Grunt Workers.

So I want to be really clear. This was a speculative theory.

I mean, and I liked it too. And we still don't know for sure, but we can, what we liked about it. So let me take a step back. So we usually assume that dark matter is what we being physicists, that it's just one thing. It's just basically non-interacting aside from gravity or very weakly interacting matter.

#403 – Lisa Randall: Dark Matter, Theoretical Physics, and Extinction Events

But again, we have to get outside the mindset of just humans and ask what else could be there. And so what we suggested is that there's a fraction of dark matter, not all the dark matter, but some of the dark matter, maybe it has interactions of its own. Just the same way in our universe, we have lots of different types of matter. We have nuclei, we have electrons, we have forces.

It's not a simple model, the standard model, but it does have some basic ingredients. So maybe dark matter also has some interesting structure to it. So maybe there's some small fraction.

And the interesting thing is that if some of the dark matter does radiate, and I like to call it dark light because it's light that we don't see but dark matter would see, it could radiate that and then it could perhaps collapse into a disk the same way ordinary matter collapsed into the Milky Way disk. So it's not all the dark matter, it's a fraction.
