1950 yılında, john synge schwarzschild metriğin maksimal analitik uzantısını gösteren, yeniden r = rs de tekilliğin bir koordinat işlem hatası olduğunu ve iki horizonla gösterildiğni gösteren bir makale yayınladı.
in 1950, john synge produced a paper that showed the maximal analytic extension of the schwarzschild metric, again showing that the singularity at "r" = "r"s was a coordinate artifact and that it represented two horizons.

kerr metrik 1916 yılında karl schwarzschild'le tarafından keşfedilen ve bir yüksüz, küresel-simetrik çevresindeki uzay geometrisini açıklar ve vücudu dönmeyen oldu schwarzschild metrik, bir genelleme olduğunu.
the kerr metric is a generalization of the schwarzschild metric, which was discovered by karl schwarzschild in 1916 and which describes the geometry of spacetime around an uncharged, spherically-symmetric, and non-rotating body.

uygun uzay zaman modelleri ( ya dış schwarzschild çözümü ya da birden fazlatek kütle için post-newtoncu genleşmesi ) açıklandığı üzere, yerçekimininışığın ortaya dağılmasındaki birçok etkileri.
as one examines suitable model spacetimes (either the exterior schwarzschild solution or, for more than a single mass, the post-newtonian expansion), several effects of gravity on light propagation emerge.
