Title: Stringy nonlocality and black hole horizons

Abstract: Strings are believed to spread out when observed at high energy. I'll discuss several approaches towards deriving this result, which I worked out in papers with Eva Silverstein and Gonzalo Torroba. The first is based on an analysis of the six-point scattering amplitude in string theory, and the second is based on tracing string interactions using a background dilaton field. Then I'll discuss applications to horizon physics, which are predicated on large boosts between an early infaller and a late observer.
