Abstract Along the geodesic we calculate the interference phase of the mass neutrinos propagating in the radial direction in Robertson--Walker space--time. Since our universe is expanding, the phase factor $\varPhi$ is increasing under the condition of the same proper physical distance l. Different values of curvature parameter k in Robertson--Walker metric represent different cosmological models, correspondingly, we obtain the different interference phases.

Altmetric calculates a score based on the online attention an article receives. Each coloured thread in the circle represents a different type of online attention. The number in the centre is the Altmetric score. Social media and mainstream news media are the main sources that calculate the score. Reference managers such as Mendeley are also tracked but do not contribute to the score. Older articles often score higher because they have had more time to get noticed. To account for this, Altmetric has included the context data for other articles of a similar age.
