But! This bulgy “ellipsoid” Earth isn't the whole story either.

但椭圆的地球并不是我们要探讨的全部内。

In 2006, data gathered by Nasa's Wilkinson satellite suggested that the Universe itself may be an ellipsoid — an oval.

2006 年，美国国家航空航天局的威尔金森卫星收集的数据表，宇宙本身可能是一个椭圆体——椭圆形。

These dense lumps of rock bump out from the ellipsoid and their mass gravitationally attracts oceans, while valleys in the ocean floor have less mass and the oceans flow away, shallower.

这些稠密的岩椭球体中碰撞出来，它们的质量在引力作用下吸引着海洋，而海床上的峡谷质量较小，上方的海水也因此流走。
