By Marcus Chown IT IS the ultimate cosmic villain: space and time come to an abrupt end in its presence and the laws of physics break down. Now it seems a “naked” black hole may yet emerge in our universe, after spinning away its event horizon. In 1969, physicist Roger Penrose postulated that every singularity, or black hole, must be shrouded by an event horizon from which nothing, including light, can escape. His Cosmic Censorship Conjecture has it that singularities are always hidden. If the conjecture doesn’t hold,
