So as I have two of these things in the hallway, I headed into the bathroom at the Speyer Legacy School, but there's not such great acoustic insulation between the hallway and the bathroom. And as soon as I disappeared from the scene, the kids start asking each other well what's this and what's that? The question becomes how do we have a map of dark matter? It's dark, how do we know where it is with that kind of specificity? And I was astounded that very quickly, the third and fourth graders figured out that you use the gravitational lens—that's one way of doing this—to figure out where the distortions in space and time are, and indirectly infer the position of the dark matter by its effect on visible light, which is a very advanced idea for people who don't know the Einstein field equations.
