The Floor

Every theory the sciences and mathematics actually run on, joined by what it rests on, what limits it, and what shares its form. One body, so you can walk from any theory to the ones holding it up. Drawn rather than listed, because a list cannot show you what is missing — you would have to already know.

The same floor, read the other way, is The Floor of Discovery — Scripture and the created order as one design. That page is for seeing it; this one is for walking it.

Where the floor is missing

A lattice, because a lattice has sites that can be empty. Eight dimensions down, the catalogue's sections across; each site asks what a section contributes to a dimension, and a dashed red cell is that question with nothing on the shelf to answer it. An empty site is a question, not automatically a gap — some combinations need not exist — but a whole row of them is a thin place worth walking to.

How well each theory is joined

The same 178, arranged by how many relations each holds — most aligned at the centre, spiralling out at the golden angle. Distance from the middle is how peripheral a theory is to the assembled floor. Zoom in, turn it to another angle, and click any cell for its card. Changing the angle changes the question the picture is answering: by depth the centre is what we actually know most about, by calibration the sealable core separates from the map-only rim.

What the drawing is telling you

theories	178
relations	285 · every one carrying its evidence
cross-domain pairs	151
median relations per theory	3
cards with real depth	178 of 178 — the rest carry only the assay template, which is why the map is dim

Thin — a beam resting on almost nothing

These hold one relation or none. Not wrong; underbuilt. Each is a place to look for what it actually stands on.

Found and checked, never generated. Every relation carries the reason it exists; a relation without one is not written.
