In a galaxy far, far away (redshift z = 5.0) an electron and a positron collide and annihilate, producing two photons. The collision is nonrelativistic and the center of mass frame of the collision is at rest with cosmic expansion. An instrument mounted on an orbiting telescope with an effective diameter of 2.0 cm detects one of the photons. How accurately can the celestial position of the collision be determined?
