The principle of holography of information tells us that, in a theory of quantum gravity in asymptotically flat space, all operators on future (past) null infinity can be approximated near its past (future) boundary. However, massive fields do not have a good limit as one approaches null infinity. In this talk, I will describe a novel asymptotic limit of massive fields at the blowup of spatial infinity that leads to a well-defined algebra of boundary operators. I will discuss how the extrapolation procedure must be improved in the presence of interactions. We will conclude with a conjecture for how holography of information might be generalized to incorporate massive fields.
