The Compounding

The electromagnetic coupling constant α_em measures the probability that the break couples to itself through one channel. One face, one dimension, one interaction. It is the strength of ε reading itself through the phase face. Numerically α_em ≈ 1/137 — a dimensionless ratio, no units, the probability of interaction per channel.

Now ask: what is the total coupling strength through all 21 channels simultaneously? The channels are independent — they must be, because each corresponds to a different face-projection or actualisation coupling, and the independence of the faces (AP24) and of the spatial dimensions (AP10) are derived results.

For independent channels, simultaneous coupling is multiplicative. This is not a physical assumption. It is a mathematical fact about independent events. If the probability of passing through channel 1 is p, and through channel 2 independently p, then through both it is p × p. Through all 21: p²¹.

The electromagnetic coupling is one channel: α_em. The gravitational coupling requires all 21 channels simultaneously — because gravity maintains the entire arena. Not one face. Not one dimension. All of them. Every room in the building. The break persists across the whole structure, or the structure collapses and the break heals. Axiom R does not permit selective persistence. The crack is open everywhere or nowhere.

Therefore the gravitational coupling through the paired channels is α_em²¹ ≈ 1.338 × 10⁻⁴⁵. This is the 1:1 of the gravitational constant — the balanced structure. Twenty-one paired channels, each compounding the suppression by one power of the electromagnetic coupling.
