Surface Tension of Cosmic Voids as a Possible Source for Dark Energy

Abstract

The cosmological constant is estimated by considering the surface tension of supervoids in a void-dominated cosmic fluid by which we can get a possible source of dark energy. Looking at voids as bubbles, we define the concept of surface tension which is shown to have an almost constant value for supervoids that are enclosed by superclusters. The surface tensions of voids are computed by dimensional method for galaxies and superclusters with different values for each group. At large scale which vast voids are dominant the positive cosmological constants obtained of order $(\simeq +10^{-52}{\mathrm{m}}^{-2})$, which are very close to those given by $Planck$.
