Abstract
Sakharov's conjecture that the vacuum is densely occupied with Planck-mass maximons is taken as a model to explain the missing mass as rotons of a superfluid made up from the Planck-mass maximons. Because rotons require a finite excitation energy, they not only can account for the missing mass but, in addition, can mimic a small, positive cosmological constant. According to Sakharov, the large vacuum energy of the Planck-mass maximons is compensated by “ghost particles.” In the proposed superfluid vacuum model, we assume that the compensation is done by a large, negative cosmological constant instead.
