月亮的错觉

One of the first ideas suggested was that the image of the moon in the sky really is bigger near the horizon.

较初的一种观点是月亮在空中时成的像确实比接近地平线时大一些。

Perhaps the Earth's atmosphere acts like a giant lens, magnifying the moon as it rises and sets.

或许地球的大气层就像一面巨大透镜，在月亮升起和降落时放大它的图像。

But this explanation doesn't cut it.

但是这个解释并不合理。

If anything, the refraction of the atmosphere would make the moon look slightly smaller.

如果真有大气层折射，它应该是让月亮看起来小一点儿。

Plus, if you actually measure the size of the visible moon at different positions, it doesn't change at all.

而且，如果你真的在不同地点测量月亮可见部分的尺寸，会发现它没有变化。

But then, why does it still seem bigger when it's rising?

那么，为什么月亮升起时会显得大一些呢？
