| Abstract: | We discuss the existence, arising by analogy to that in algebraically special space-times, of a unique asymptotically shear-free
congruence in any asymptotically flat space-time. Associated with it is a unique complex analytic curve in H-space. The surprising
potential physical significance of this curve is discussed.
