Null Geodesic Congruences, Asymptotically-Flat Spacetimes and Their Physical Interpretation
A priori, there is nothing very special about shear-free or asymptotically shear-free null geodesic congruences. Surprisingly, however, they turn out to possess a large number of fascinating geometric properties and to be closely related, in the context of general relativity, to a variety of physica...
