The shape of the earth? The heliocentric universe? The Pythagorean theorem? The structure of DNA?

放弃对地球形状的认识？对以太阳为中心的宇宙的认识？还是对勾股定理的认识？对DNA结构的认识？

And you can also see that the collision has substantially distorted the shape of the Earth itself.

同样能够看到，撞击严重扭曲了地球本身的形状。

The bridge is so long that the shape of the earth had to be taken into account by its designer.

由于桥身太长，设计者不得不考虑了地表的形状。

They also knew the shape of the Earth's shadow was always a circle, which only makes sense if the Earth were a sphere.

他们还知道，地球的阴影总是圆形，这当然只有在地球是一个球体的情况下才成立。

If you wanted to be absolutely precise, you could use an equation that takes into account the roughly spherical shape of the Earth.

如果你想绝对精确，你可以使用一个考虑到地球大致球形的方程。

But if you know a little geometry, you can use the size and shape of the Earth's shadow on the Moon to get the relative sizes of the Earth and Moon.

不过如果你了解一些几何学，你就可以通过地球投射在月球上的阴影的大小和形状来算出地球相对于月球的大小。

So something like the sun that's bigger than the Earth and is able to cast a shadow of the Earth on the moon can actually show you the shape of the Earth.

像太阳这种比地球大的东西，能够在月球上投射地球的阴影，从而真实地给你展示地球的形状。
