Probing the Effects of Nonviolent Nonlocality with Gravitational Waves*

Measurement of gravitational waves can give precision tests of the nature of black holes and compact objects. Gidding’s nonviolent nonlocality is motivated by the information paradox and allows the information to escape via soft modes in a black hole atmosphere. Furthermore, these soft modes could exist at distances of around a Schwarzschild radius beyond the horizon. In this talk, we will discuss how to probe soft metric fluctuations near the horizon by observing the inspiral of a binary black hole. We use an effective one body model and evaluate the dynamics with added noisy metric fluctuations. We find that during the late inspiral-merger, the binary exhibits random dephasing. We also find that the parameterized post-Einsteinian coefficients will be randomly distributed depending on the noise realization, from which we constrain the size of the metric fluctuations by combining many events.
