Stretched extra dimensions and bubbles of nothing in a toy model landscape

Abstract

Using simple 6D junction conditions, we describe two surprising geometries. First in a case of transitions between dS4xS2 vacua, the S2 can be stretched significantly larger than the vacuum values both before and after the transition. Then we discover that the naive instability to decompactification is actually a bubble of nothing instead.
