(Laughter) And this is essentially what that clustering in argument of perihelion was telling us.

（笑声） 这基本上就是近日点参数的聚集告诉我们的。

These objects really did all share a common value of argument of perihelion, and they shouldn't.

这些天体确实都具有共同的近日点角角值，但它们不应该如此。

When they realized it was clustered in argument of perihelion, they immediately jumped up and down, saying it must be caused by a distant, giant planet out there, which is really exciting, except it makes no sense at all.

当他们意识到这是聚集在近日点的争论中时，他们立即跳上跳下， 说这一定是远处一颗巨大的行星造成的，这真是令人兴奋， 只是毫无意义。
