The Return of the String

Abstract: Two applications of worldsheet string theory illustrate the structure of string theory near the threshold of black hole formation. In the first, we consider string probes of horizonless microstate geometries and find that strong tidal forces cause infalling strings to become trapped, mimicking the absorptive properties of black holes. In the second, we re-examine the structure of (near) BPS microstates and find a mechanism whereby the geometrical description breaks down.
