  This essay presents a new asymmetry that arises from the interplay of charge
conjugation and Lense-Thirring effect. When applied to Majorana neutrinos, the
effects predicts nu_e <-> overline{nu}_e oscillations in gravitational
environments with rotating sources. Parameters associated with astrophysical
environments indicate that the presented effect is presently unobservable for
solar neutrinos. But, it will play an important role in supernova explosions,
and carries relevance for the observed matter-antimatter asymmetry in the
universe.
