Inside the Resonant Cavity
Companion to The Atom Is E₈. Every atom is a resonant cavity with two chambers — one for protons, one for neutrons — joined by a shared wall and cut by internal Galois boundaries. Three new derivations agree with experiment to better than one percent.
Key Results
The cavity is the space
The parent paper proved that atomic architecture is E₈ and reproduced all seven nuclear magic numbers. This companion takes up what was left open: the deuteron binding energy, the Higgs mass, and the full spectrum of permitted standing waves. The cavity has two chambers (protons, neutrons), a shared wall (the D₄ bridge), and an internal boundary cutting each chamber (the Galois surface of ℚ(√5)). Particles are the waves the cavity admits. Forbidden waves are what we call empty space.
1
The deuteron binding energy equals the pion mass divided by sixty — the geometric fraction of the shared wall connecting the two chambers.
2
Particles are the cavity's standing waves. Empty space is the forbidden waves. There is no vacuum surrounding the atom into which it radiates; the cavity is the space.
3
The Galois boundary of ℚ(√5) inside each chamber separates 94 confined (rational) eigenvalues from 26 free (irrational) eigenvalues — the electron's internal surface.
4
Three independent derivations (deuteron binding, meson spectrum, Higgs mass) each agree with measurement to better than one percent.
Kill Conditions
K1: Deuteron binding prediction deviating from mπ/60 by more than 0.5% — cavity model fails
K2: Any of the three new derivations landing outside ±1% of experiment — architecture falsified
K3: Detection of a persistent standing wave forbidden by the cavity spectrum — geometry falsified
