In asymptotically flat space, the principle ? ?of holography of information states that, in a theory of quantum ? ?gravity, all operators on future (past) null infinity can be ? ?represented near its past (future) boundary. However, massive fields ? ?do not have a good limit as one approaches null infinity. In this ? ?talk, we will discuss a novel asymptotic limit of massive fields at ? ?the blowup of spatial infinity that leads to a well-defined algebra ? ?of boundary operators. We will show how the extrapolation-procedure ? ?must be improved in the presence of interactions and describe the ? ?relationship between the algebra at spatial infinity and the ? ?standard "in" and "out" algebra. We will briefly ? ?discuss a conjecture for how holography of information might be ? ?generalized to incorporate massive fields. ?
