  Bubbles of nothing are a class of vacuum decay processes present in some
theories with compactified extra dimensions. We investigate the existence and
properties of bubbles of nothing in models where the scalar pseudomoduli
controlling the size of the extra dimensions are stabilized at positive vacuum
energy, which is a necessary feature of any realistic model. We map the
construction of bubbles of nothing to a four-dimensional Coleman-De Luccia
problem and establish necessary conditions on the asymptotic behavior of the
scalar potential for the existence of suitable solutions. We perform detailed
analyses in the context of five-dimensional theories with metastable
$\text{dS}_4 \times S^1$ vacua, using analytic approximations and numerical
methods to calculate the decay rate. We find that bubbles of nothing sometimes
exist in potentials with no ordinary Coleman-De Luccia decay process, and that
in the examples we study, when both processes exist, the bubble of nothing
decay rate is typically faster. Our methods can be generalized to other
stabilizing potentials and internal manifolds.
