There may exist a parallel mirror world, a hidden sector of particles which has exactly the same microphysics as the observable world and couples to the latter by gravity, and perhaps other very weak forces. Any neutral observable particle, elementary or composite, can have a mixing with its mirror partner, with rather interesting consequences for the particle physics and cosmology, in particular regarding lepton and baryon number violation, baryogenesis and dark matter.
