Furthermore, as can be seen in figure 3.5, any deviation of the Higgs fields from their false-vacuum values would require an increase in energy density. This implies that the false vacuum has a peculiar property which distinguishes it from all familiar materials: when the volume of a region of false vacuum is increased, the energy density cannot decrease, but instead remains at a constant value."
