In this talk, I will explore the physical mechanisms responsible for generating the graviton pole in twice-subtracted dispersion relations. These mechanisms are characterized by an energy scale at which the graviton pole is generated at fixed impact parameters. At large impact parameters, the eikonal model of high-energy gravitational scattering is identified as a universal mechanism that generates the graviton pole in dispersion relations. At smaller impact parameters, the graviton pole can arise from stringy higher-spin resonances. I will then discuss a Tauberian theorem for the graviton pole, which must be satisfied by any UV completion of gravity that admits twice-subtracted dispersion relations.
