Parity test of gravitation

(68.5.243.16)
More readable (4000 words of text), more data (15.6 quadrillion atoms explicitly calculated, up from 0.33 quadrillion), better convergence of model vs. calculation.
Metric models are geometric, postulate the Equivalence Principle, and have geodesics. Affine models are electromagnetic in form, ignore the Equivalence Principle, and have no geodesics. All metric theory predictions are included in affine theories.
Teleparallel gravitation.
Metric and affine theories have a slim non-interesection of disjoint predictions. The way to tell which is The One is to look at the disagreements, not at the agreements.
Einstein's metric General Relativity is a tensor theory of gravitation that is symmetric to parity transformation. Affine theories, teleparallel gravitation, can possess gravitational stress-energy pseudotensors that are anti-symmetric to parity transformation.
AN OBVIOUS INQUIRY IS TO TEST THE EQUIVALENCE PRINCIPLE AGAINST PARITY-TRANSFORMED TEST MASSES. This point seems to have been lost on physics despite its trivially easy and inexpensive implimentation in existing apparatus.
