Rethinking Parity Interpretation in the Wu Experiment

The 1957 Wu experiment is widely believed to have demonstrated parity violation in weak interactions. However, this conclusion was drawn by comparing a real system to an imagined mirror image that was never physically constructed. This essay argues that parity violation was never empirically measured but inferred through symbolic projection. Without a constructible mirror world, claims of symmetry breaking lack experimental grounding. We propose a shift in standard practice: symmetry claims must meet a “constructibility condition” to be physically meaningful.
