Abstract
The vacuum bubbles in the curved spacetime are analyzed. We classify the true and false vacuum bubbles with the cosmological constants from the minimum of the potential being either positive, zero, or negative. We introduce new type of solutions with Z2 symmetry when the potential has degenerate vacua, i.e., instanton solutions. This new type of solutions are possible only if gravity is taken into account.
