Stopping atoms A "coil-gun" method for slowing atomic beams without lasers, from the Raizen group at Texas

Breslow's argument includes a 10,000 C plasma fireball upon meteorite impact, a poor start for organic synthesis. Chiral protein amino acids are L-configuration, natural chiral sugars are D-configuration. Pookie pookie.

Replace achiral pseudo-Riemannian spacetime curvature with chiral Weitzenböck spacetime torsion. Obtain a chiral vacuum background differentially active only toward mass configuration - EM is inert. General Relativity works to spec given no natural resolved chiral bodies (meat and wood cancel on Earth). The chiral vacuum effect is 10^(-12) relative or smaller post-inflation.

Massed sector chiral vacuum is testable. A parity Eötvös experiment opposing chemically identical cultured solid single crystal quartz would do it: one set of test masses in space group P3(1)21 (right-handed screw axes) and the other in space group P3(2)21 (left-handed screw axes).

Somebody should look.
