Uptunneling to de Sitter
  We propose a Euclidean preparation of an asymptotically AdS$_2$ spacetime
that contains an inflating dS$_2$ bubble. The setup can be embedded in a four
dimensional theory with a Minkowski vacuum and a false vacuum. AdS$_2$ times
2-sphere approximate the near horizon geometry of a $4d$ near-extremal RN
wormhole. Likewise, in the false vacuum the near-horizon geometry of a
near-extremal black hole is approximately dS$_2$ times 2-sphere. We interpret
the Euclidean solution as describing the decay of an excitation inside the
wormhole to a false vacuum bubble. The result is an inflating region inside a
non-traversable asymptotically Minkowski wormhole.
