Abstract: We comment on the interpretation of absolute rotation measurements withsuperfluids, which involve the Sagnac effect. This effect, first observed inrotating optical interferometers, has now been seen in a host of differentphysical systems, ranging from atomic clocks to electrons, neutrons, atomicbeams,

. We show that the time-honored explanation of this effect based ongeneral relativity provides a common explanation for all these systems,including superfluids, in contradistinction with the views expressed in arecent review article.
