How to detect an anti-spacetime [PDF]
Marios Christodoulou, Aldo Riello, Carlo RovelliIs it possible, in principle, to measure the sign of the Lapse? We show that fermion dynamics distinguishes spacetimes having the same metric but different tetrads, for instance a Lapse with opposite sign. This sign might be a physical quantity not captured by the metric. We discuss its possible role in quantum gravity.View original: http://arxiv.org/abs/1206.3903
