Reverse Physics Approach Derives Laws from Mathematical Structures to Reconcile Quantum-Classical Divide
Reverse physics inverts the standard discovery sequence by starting from pure mathematics to generate physical laws. The goal is a derivation of the quantum-classical boundary that does not rely on ad-hoc measurement postulates. Current work is formal only; empirical mapping to measurable quantities is required before any technological relevance can be assessed.
Standard physics proceeds from observation to mathematical formalization, yet persistent measurement problems and the quantum-to-classical transition lack a unified derivation. The reverse method instead posits category-theoretic or algebraic structures first, then extracts dynamics and observables that must match known phenomena only at the end. This inverts the usual epistemic order and could expose hidden assumptions in Hilbert-space or phase-space formulations. Early sketches suggest emergent classicality arises when certain functorial constraints are imposed, but no laboratory signature has been calculated. The approach remains entirely formal and risks generating internally consistent yet physically empty theories unless concrete observables are derived and tested against existing interferometry or decoherence data within controlled parameter regimes.
Padavic-Callaghan: By 2028 at least one reverse-physics model will yield a falsifiable prediction for decoherence timescales in mesoscopic systems differing by more than 20% from standard quantum predictions.
