The Aether unit \(A_u\) is the rotational constant used in QADI/APM to express the geometric structure underlying electromagnetic propagation and Ledger One closure.
Definition
In the QMU ledger, the Aether unit is defined as Coulomb's constant scaled by the full circular factor \(16\pi^2\).
Ledger One role
The Aether unit participates directly in the rotational self-identity:
Since \({F_q}{\lambda_C}=c\), the product \(A_u\cdot\mathrm{curl}\) provides the QMU factorization of the electromagnetic propagation constant into Aether rotational geometry and torsional response.
Interpretive function
\(A_u\) functions as a geometrically expanded Coulomb constant, allowing charge relations to be expressed through rotational closure rather than only through linearized SI projection.
