Even though there are no words that can explain what love is, we all know what love feels like... all warm and bubbly with golden light and... why, it's similar to the feelings we get each spring.
尽管爱没有语言能够解释，我们都熟悉爱的感觉……温暖备至，充满生机，金光熠熠，还有……对了，爱恰似我们在每个春天里的感觉。
So, as we look further and further away, it takes longer and longer for the light to get from where it's emitted to here and we can actually see backwards in time.
因此，当我们观测的距离越远，光线传播到那里花费的时间也越长。因此我们能够看到时光倒流。
We can get a rough idea of the metals to light by making a few gross simplifying assumptions.
我们做几个粗糙的简化假设，就能够得到关于金属对光的反应的一个大致的概念。
