We comment on the interpretation of absolute rotation measurements with superfluids, which involve the Sagnac effect. This effect, first observed in rotating optical interferometers, has now been seen in a host of different physical systems, ranging from atomic clocks to electrons, neutrons, atomic beams, ... We show that the time-honored explanation of this effect based on general relativity provides a common explanation for all these systems, including superfluids, in contradistinction with the views expressed in a recent review article.
