Abstract
We consider a finitesize spherical bubble with a nonequilibrium value of the qfield, where the bubble is immersed in an infinite vacuum with the constant equilibrium value q_{0} for the qfield (this q_{0} has already cancelled an initial cosmological constant). Numerical results are presented for the time evolution of such a qbubble with gravity turned off and with gravity turned on. For small enough bubbles and a qfield energy scale sufficiently below the gravitational energy scale E_{Planck}, the vacuum energy of the qbubble is found to disperse completely. For large enough bubbles and a finite value of E_{Planck}, the vacuum energy of the qbubble disperses only partially and there occurs gravitational collapse near the bubble center.
