As a snowflake falls, changes in weather conditions can affect how it grows, and even small differences in the paths two snowflakes take will differentiate their shapes.

当花飘落，大气条件的变化会影花如何生长，即使是两片花飘落路径中极微小的异也会使它们的形状有所不同。

And so if we can detect very, very slight changes in the time between pulses, not from one pulsar but from any pulsars all around the sky, then we can hope to find these correlation patterns between pulsars.

所以，如果我们能探测脉冲间隔时间的极微小变化——不是一颗脉冲星的，而是天空中所有的脉冲星的——那么我们就有希望找脉冲星之间的相关模式。
