So it is possible that the value that the Higgs field has, even though it is lower energy density than it would at zero, is still not the lowest energy density that it could have. If that's true, it opens up the possibility of vacuum decay. There could be a little bubble, a very, very, very, very tiny bubble where the Higgs field takes on a much larger value than it currently has.
