General Relativity is trivially falsifiable without contradiction. SR becomes GR by postulating the Equivalence Principle. Present two lumps that locally vacuum free fall along non-parallel trajectories and GR is reduced to a heuristic. The lab bench EP gold standard is the Eötvös experiment with 5×10^(-14) difference/average sensitivity. All compositions of matter (including massive relativistic and quantum mechanical distortions of PSR J0737-3039A/B) obey GR and validate the EP. So what? Gravitation is mass configuration. Are chemically identical left and right shoes an EP parity violation?

(Parity violating massed sectors are neither required nor forbidden in metric-affine, Einstein-Cartan, teleparallel, and Riemannian geometry gravitations. Ashtekar has a parity violating term with the Immirzi coefficient. Theory sypporting EP parity violation is already in place.)

230 periodic 3-D crystallographic space groups. 65 Sohncke space groups can contain chiral contents. 11 pairs of Sohncke space groups are enantiomorphs (opposite shoes) – the space groups themselves are chiral independent of the contents. Enantiomorphic space groups P3(1)21 and P3(2)21 (quartz group) calculate as maximally parity divergent. Do the opposite parity atomic mass distributions of enantiomorphic single crystal alpha-quartz test masses measurably violate the Equivalence Principle in a parity Eötvös experiment? Somebody should look. It’s slick crackpottery… unless it works. Validation promotes it to discovery.

(There is no parity Nordtvedt effect re lunar laser ranging. Chiral L-amino acids in protein, chiral D-sugars naturally, then meat and wood cancel. All non-life chiral materials are spontaneous racemic mixtures.)
