月亮的错觉

But when the moon is higher up, it's surrounded by the vast darkness of the night sky and looks tiny by comparison.

而当月亮在高空中时，它被茫茫黑夜环绕，所以相对来说显得小了。

Another possibility is the famous Ponzo Illusion.

另一种解释是的庞佐错觉。

If you've ever tried to draw in perspective, you know that the closer something is to the horizon, the smaller you should draw it.

如果你曾经试过透视画法就会知道，一样东西越靠近地平线就该画得越小。

Our brain compensates automatically for this by perceiving objects near the horizon as larger than they actually appear.

我们的大脑自动弥补了这样的透视效果，使得地平线附近的物体在我们脑海中的形象比实际更大。

The two yellow lines in this drawing are the same size, but the upper one seems bigger because we interpret it as receding farther into the horizon.

这幅画里两条黄线是一样的尺寸，但上面那一条看起来更长，因为我们觉得它更接近地平线，所以应该比画里面显得更长。
