Understand

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.
