…Of the above solutions, only the Kerr solution has a structure in which the singularity is surrounded by the event horizon. Conversely, if we prohibit the existence of singularities outside the event horizon (called naked singularities) (called the cosmic censorship assumption), it has been shown that the axisymmetric stationary solutions are limited to the Kerr solution (uniqueness theorem). General relativity breaks down at singularities. … *Some of the terminology used in reference to the "cosmic censorship hypothesis" is listed below.

…上記の解のうち,カー解のみが,特異点が事象の地平面に囲まれているという構造をもつ。逆に,事象の地平面の外側に特異点が存在すること(裸の特異点と呼ばれる)を禁止すると(宇宙検閲仮定という),軸対称定常解は,カー解のみに限ることが示されている(唯一性定理)。特異点においては一般相対論は破綻(はたん)している。… ※「宇宙検閲仮定」について言及している用語解説の一部を掲載しています。 出典|株式会社平凡社世界大百科事典 第2版について | 情報 |
