假如的确不存在，那也是因为物理学定律没有让你把时空扭曲到一定程度来创造这些曲线，并不是因为定律让你的祖父在你出生前就夺去你的生命。
If that is true, though, it is because the laws of physics do not let you warp space-time enough to create them-not because they let you kill your grandfather before you are born.
与封闭的时间型曲线相关的这种扭曲会导致我们的切分转回原处，不可能把所有的时空分成各自不同的时刻。
The warping associated with the closed timelike curve could cause our slice to twist back on itself, making it impossible to divide all of space-time into distinct moments.
但仔细观察会发现许多背景上的星系都由于该星群的引力透镜的偏斜而被扩大并扭曲成怪异的长条弧状曲线。
A close inspection, however, shows that many background galaxies are strangely magnified and distorted into long curving arcs by the gravitational lens deflections of the cluster.
