Effective Field Theory islands from perturbative and nonperturbative four-graviton amplitudes

Abstract Theoretical data obtained from physically sensible field and string theory models suggest that gravitational Effective Field Theories (EFTs) live on islands that are tiny compared to current general bounds determined from unitarity, causality, crossing symmetry, and a good high-energy behav...
