For spatial infinity we introduce the topology of a projective Lorentz sphere. This topology is indicated by the reduced variety of physically admissible solutions of both the electromagnetic and the gravitational field equations. In this topology past and future are fused, so that the notions of cause and effect lose their intuitive meanings.
