Mass as resistance

Mass is not substance. Mass is geometric resistance — the structural opposition a record offers to displacement, change, or acceleration. A particle with mass m resists m times more than a particle with unit mass.

The unit of resistance is set by the minimal break: the electron, mass m_e (Axiom B, AP06).

The 420 Code numbers

21: the number of geometric channels through which the break persists (AP10 + AP28). These arise from the combinatorial structure of three spatial dimensions resolved from one manifold.

3: the number of faces of the manifold (AP10). Identified with the three colours of SU(3) (AP19). Each face corresponds to one of three structural roles: C (Constraint — locality, read as propagation), S (Symmetry, read as exchange), B (Break).

4: the number of spacetime dimensions into which the manifold resolves (AP10, AP20). Three spatial + one temporal.

α_em = 1/137.036: the fine structure constant, identified as ε — the leakage constant, the substrate’s fundamental coupling strength (AP06). This is the rate at which the substrate’s minimal break couples to its own field.
