Testing Spacetime Orientability

Abstract Historically, a great deal of attention has been addressed to the question what it would take test experimentally metrical structure spacetime. Arguably, however, consideration this at expense comparable investigations into other structural features In article, we critique and expand substantially upon an article by Hadley (Hadley in Class Quantum Gravity, 19:4565–4571, 2002), which constitutes one best-known paper-length studies orientability so doing, seek clarify number matters remain unclear wake Hadley’s thereby allowing literature on topic progress. More positively, also present, compare, evaluate potential approaches testing spacetime have arisen recent physics literature.
