The angular distribution of neutrinos and antineutrinos emitted by a rotating black hole is asymmetric. More antineutrinos are emitted in the direction parallel to the hole's angular momentum; more neutrinos in the antiparallel direction. This result applies not only to black holes, but to any rotating star emitting thermal neutrinos. Emission of other particles can also be asymmetric as a result of parity-nonconserving weak interactions.
