另一种可能性是加速膨胀不是来自物质而是修改的重力形式，其作用在时空的宇宙尺度上是不同的。

Another possibility is that the accelerated expansion arises not from a substance but from a modified form of gravity, one that behaves differently on cosmic scales of time and space.

你要寻找一个在这个景观中特有的元素，并以此作为一个表现景观物质并能显示景观尺度的兴趣点。

Look for an element peculiar to that place and use it as a point of interest that says something about the scene and imparts a sense of scale.

这种形式的物质在宇宙学尺度上也是无关紧要的，对膨胀或坍缩几乎没有贡献。

This form of matter also has no cosmologically significant pressure.

But once we got to the atomic size scale, what happens is we need to be taking into account the fact that matter has these wave-like properties, and we'll learn more about that later, but essentially classical mechanics does not take that into account at all.

但一到到了原子尺度量级，我们必须考虑到物质,这时候有波动性质,关于这点我们今后将会学到更多,但本质上经典力学并,没有考虑这个性质。
