Abstract: I will discuss my PhD research with Eva Silverstein on black hole horizons and string theory. Off-shell calculations suggest that the longitudinal extent of a string grows linearly with energy. We tried to derive this in a gauge-invariant way by analyzing the scattering matrix, specifically a certain six point function. Assuming this result, we can apply the longitudinal spreading effect to the near-horizon region of a black hole, which I will argue leads to a violation of effective field theory. This may have interesting consequences for Hawking's information paradox. If I have time I'll talk about work in progress on classical string solutions.
