3740por Bellazzini, Brando, Isabella, Giulia, Lewandowski, Matthew, Serra, Javi, Sgarlata, Francesco“…Our results show that, at first post-Minkowskian order, asymptotic causality, where the time delay experienced by any particle must be positive, is respected quantum mechanically. Contrasted with asymptotic causality, we explore a local notion of causality, where the time delay is longer than the one of gravitons, which is seemingly violated by quantum effects.…”
