In 2001, a satellite called WMap took a photograph of our entire sky to capture this ancient light.

2001 年，一颗名为 WMAP 的卫星拍下了整个天空的照片，以捕捉这些古老的宇宙光波。

They were seeing the first photons-the most ancient light in the universe though time and distance had converted them to microwaves, just as Gamow had predicted.

他们在观望第一批质子--宇宙中最古老的光--果然不出伽莫夫所料，时间和距离已经将其转变成了微波。

The reason we can't see this ancient light is because, as the universe expanded, the light waves were stretched and transformed into radio waves and microwaves.

我们之所以看不到这道远古的光，是因为随着宇宙膨胀光波被拉伸 、变形，成为了广播波和微波。

So whether you're basking in the young light of the noonday sun, or standing under the ancient light of the stars at night, remember you're always bathed in the forever-light of the cosmic afterglow.

因此， 无论你是沐浴在正午阳光的年轻光芒中，还是站在夜晚古老的星光下，请记住你始终沐浴在宇宙余辉的永恒之光中。
