I will present a scattering theory for the Einstein vacuum equations in the region near spacelike infinity of an asymptotically flat spacetime, constructed using a double null gauge that is Bondi-normalised at past and future null infinity. I will highlight the role of early time asymptotic behaviour near null infinity in the scattering construction, as it relates to the conjectured lack of smoothness at null infinity in physically motivated scenarios of dynamical evolution from scattering data.
