I will use the S-matrix Bootstrap to carve out the space of unitary, crossing symmetric, and supersymmetric graviton scattering amplitudes in nine, ten, and eleven dimensions. I will introduce a novel extension of positivity for massless particles dubbed “positivity in the sky” that will help to improve significantly the convergence of the bootstrap algorithm. I will show the bounds on the first leading correction to maximal supergravity, study the physics of the extremal amplitudes and compare them with the String and M-theory results.
