A result about these locations relies on an equation relating the divergence of a congruence and the Raychaudhuri scalar, which is assumed to be non-negative under either the “null energy” or “strong energy” conditions. Supercritical topological defects called cosmic strings may result in the “conical” type (-5[1])of these locations. The Eddington–Finkelstein and Kruskal–Szekeres (10[1])transformations can remove a “false” one of these (10[1])locations. These locations are characterized by “incomplete” geodesics according to the Penrose–Hawking (10[1])theorem. (-5[1])So-called “naked” (10[1])examples of these (10[2])locations (10[1])are not enclosed (10[1])by an event horizon and are theorized to not exist by the cosmic censorship hypothesis. For 10 points, name these locations in space where gravitational effects are infinite, such as in the center of black holes. ■END■ (10[2])
