But it could conceivably be a very thin disk of dark matter, a thin, dense disk of dark matter. And so then the question is, do these exist? And people have done studies now to think about whether they can find them. I mean, it's an interesting target. It's something you can measure. By measuring the positions and velocities of stars, you can find out what the structure of the Milky Way is.

But the fun proposal was that the solar system orbits around the galaxy. And as it does so, it goes a little bit up and down, kind of like horses on a carousel. And the suggestion was every time it goes through, you have an enhanced probability that you would dislodge something from the edge of the solar system in something called the Oort cloud.

So the idea was that at those times you're more likely to have these cataclysmic events, such as the amazing one that actually caused the last extinction that we know of for sure.

What really is amazing, I mean, I talk about this in Dark Matter and the Dinosaurs. It's just an amazing scientific story because it really is one of the real stories that combine together different fields of science. Geologists at the time were, you know, People thought that things happened slowly and this would be a cataclysmic event.

And also, I have to say, you know, if you think about it, it sounds like a story like a five-year-old would make up. Maybe the dinosaurs were killed by some big rock that came and hit the earth. But then there really was a scientific story behind it. And that's also why I like The Dark Desk, because there's a scientific story behind it.

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.
