阿尔伯特.爱因斯坦在其广义相对论中对此已有预测，他指出密度极高，质量极大的物体相互靠近到一定程度时就会出现上述现象。

They were predicted by Albert Einstein as part of his theory of general relativity and expected to be generated whenever extremely dense and massive objects get too close to each other.

这一现象是指光线在时空中传播的过程中由于大质量物质的引力而发生弯曲，这也是爱因斯坦的广义相对论所预言的。

This phenomenon, predicted by Einstein's theory of general relativity, causes light to curve as it flies through space-time that has been dented by the gravity of large bodies of mass.
