What persists is not what moves. What moves is organized by what stays.
Constructor Theory (David Deutsch): Physics is not about what happens but about which transformations are possible and which are impossible. The impossible transformations — the null tasks — are the invisible walls that define all dynamics. Particles try random moves; some succeed, some bounce off hidden constraints. Toggle the scaffold to see the walls that ARE the physics.
Primordial Black Holes: Before any galaxy existed, naked black holes sat in the void. Matter didn’t create them — it organized around them. The anchor came first; the spiral structure is emergent. Watch particles stream inward and build a galaxy around a seed that predates everything it holds.
Large Low-Shear-Velocity Provinces: Two continent-sized thermochemical blobs have sat at the base of Earth’s mantle for over four billion years. Plate tectonics, hotspot volcanism, and kimberlite pipes organize around their edges. Convection flows around them; surface features emerge above their boundaries. The blobs are older than the dynamics they shape.

The scaffold is not hidden because it is small. It is hidden because it does not move, and attention tracks motion. The stable structure is the one you have to deduce — it is everywhere implied and nowhere visible. Galaxies imply their anchors. Tectonics implies its blobs. Dynamics implies its laws. The scaffold is what remains when you subtract everything that changes.
