Minkowski space can be sliced, outside the lightcone, in terms of Euclidean Anti-de Sitter and Lorentzian de Sitter slices. I will discuss what happens when we apply holography to each slice separately. This yields a dual description living on two spheres, which can be interpreted as the boundary of the light cone. It will be explained how the Green's function and S-matrix in Minkowski space can be reconstructed in terms of two-point functions of some putative conformal field theory on the two spheres. Based on this a Minkowski/CFT correspondence is proposed. I will also comment on the interpretation of the conformal symmetry of the CFT, and on generalizations to curved space.
