We consider examples of long-lived false vacua in quantum field theory that arise from so-called `universes'. These are protected by a ($d\ensuremath{-}1$)-form global symmetry, where $d$ is the dimension spacetime. The lifetimes set UV data: tension ($d\ensuremath{-}2$)-branes charged under ($d\ensuremath{-}2$)-form gauge symmetry. can be made parametrically long even when difference energy de...
