引力奇点 Gravitational singularity

(重定向自Gravitational singularities)

引力奇异点英语:Gravitational singularity),也称时空奇异点spacetime singularity)或奇点,是一个体积无限小、密度无限大、引力无限大、时空曲率无限大的。在这个点,目前所知的物理定律停止适用。例如大爆炸之前的宇宙奇点

当前的理论推测,当一个物体落入黑洞里并趋近位于中心的奇点时,这物体会因不同部位受到增强的吸引力而被拉长,为潮汐力,或称面条化,最终完全失去维度并无可挽回地消失于奇点。 外界观测者在安全的距离外,对这事件的观测则会完全不同。根据相对论,外界观测者会看到物体随着趋近于黑洞而变得越来越慢,最终在事件视界完全停止,而从来没有真正落入黑洞。

A simple illustration of a non-spinning Black hole and its singularity

A gravitational singularity or spacetime singularity is a location where the quantities that are used to measure the gravitational field of a celestial body become infinite in a way that does not depend on the coordinate system. These quantities are the scalar invariant curvatures of spacetime, which includes a measure of the density of matter. The laws of normal spacetime could not exist within a singularity.
