We investigate the causal structure of , the spacetime consisting of that portion of Schwarzschild space outside the event horizon. Two points, p and q in which do not lie on a common null geodesic are chronologically related if and only if their celestial spheres, P and Q have non-zero linking number in , the space of null geodesics of .
