The asymmetric electron distribution showed that weak interactions are not invariant under spatial inversion.
The source theory, law, entity, prediction, or structural claim is directly tested, supported, constrained, or established by the target experiment or observation. Experimental support is not final logical proof; the edge detail states exactly what was measured.
