Black Holes and the Swampland: the Deep Throat revelations

Understand

Multi-centered bubbling solutions are black hole microstate geometries that arise as smooth solutions of 5-dimensional $\mathcal{N}=2$ Supergravity.

• When these solutions reach the scaling limit, their resulting geometries develop an infinitely deep throat and look arbitrarily close to a black hole geometry.
• We depict a connection between the scaling limit in the moduli space of Microstate Geometries and the Swampland Distance Conjecture.
• The naive extension of the Distance Conjecture implies that the distance in moduli space between a reference point and a point approaching the scaling limit is set by the proper length of the throat as it approaches the scaling limit.
