Universe particles can have handedness {chirality, universe}|. Zero-rest-mass particles conserve chiral symmetry. Neutrinos, pions, and kaons have handedness. Other particles conserve chiral symmetry. Particles with mass can change handedness by losing mass by symmetry transformations other than chirality.
