Abstract

In this contribution we describe computational tools that permit the evaluation of multi-loop scattering amplitudes in N{script} = 8 supergravity, in terms of amplitudes in N{script} = 4 super-Yang-Mills theory. We also discuss the remarkable ultraviolet behavior of N{script} = 8 supergravity, which follows from these amplitudes, and is as good as that of N{script} = 4 super-Yang-Mills theory through at least four loops.
