Abstract Current experiment results show that neutrinos have non-zero masses and that different neutrino flavours may mix and undergo a transformation to each other. Neglecting matter effects for simplicity and by solving the Friedmann--Robertson--Walker geodesic equations of the time-like particle, we preparatively investigate the vacuum oscillation or separation of neutrinos on the cosmic scale.
