But tick marks that were ten centimeters apart are now 20 cm apart!

但是原来相距10厘米的刻度现在相距20厘米了！

When you pull on it, it gets longer, and the distance between the tick marks gets wider.

当你拉它的时候，它会变长，标记之间的距离也会变宽。

In other words, the farther away a tick mark is, the faster it appears to move away.

换句话说，刻度线离我们越远，它移动的速度就越快。

When the ruler doubles in length, the tick marks that started out a millimeter apart are now TWO mm apart.

当尺子的长度增加一倍时，原来相隔1毫米的刻度现在变成了2毫米。

The tick marks represent every day I didn't buy any of those things.

刻度线表示我每天都没有购买任何这些东西。

No tick mark is the actual center, yet no matter where you are, on the ruler, every tick mark appears to move away from you.

没有刻度是真正的中心，但无论你在哪里，在尺子上，每个刻度都似乎会远离你。

Look back at that ruler: no matter what tick mark you start with, when the ruler stretches, from that spot it looks like the tick marks are all moving away from you.

无论你开始画的是什么刻度，当尺子延伸的时候，刻度线看起来都在远离你。
