Tossup

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 of these locations. The Eddington–Finkelstein and Kruskal–Szekeres transformations (-5[1])can remove a “false” one of these locations. These locations are characterized by “incomplete” geodesics according to the Penrose–Hawking theorem. So-called “naked” examples of these locations are not enclosed by an event horizon and are theorized (10[1]-5[1])to not exist (-5[1])by the cosmic censorship hypothesis. For 10 points, name these locations in space where gravitational effects are infinite, such as in the (0[1])center of black holes. ■END■ (10[1]0[1])
