Title: Quantum Gravity S-matrix Bootstrap 

Abstract: The goal of the S-matrix Bootstrap program is to use the first principles constraints of causality, symmetries, and unitarity to explore the space of physical non-perturbative scattering amplitudes. In this talk, I will review the Bootstrap of supergraviton amplitudes in dimensions greater or equal than nine explored in https://arxiv.org/abs/2210.01502 andhttps://arxiv.org/abs/2212.00151. In doing so, I will discuss how to the Bootstrap for this problem and show how String Theory emerges from consistency conditions and canonical assumptions on the properties of relativistic, quantum-mechanical scattering. I will conclude by discussing some preliminary results showing how the numerical data collected from the Bootstrap are in agreement with old and new conjectured asymptotic properties of non-perturbative gravity amplitudes.
