Sounds ethereal, right?
听起来很空灵 不是吗
This is the sound of hydrogen, the most common element in the universe.
这是宇宙中最普遍的元素 氢的声音
It's the simplest atom,
氢是结构最简单的原子
the building block of stars,
是组成恒星的基本元素
and the stuff that turns unsaturated fat into saturated fat.
氢还能氧化不饱和脂肪酸
It also blew up the Hindenburg.
氢同样能将兴登堡号炸得粉碎
But how are we listening to hydrogen?
但我们怎么才能听到氢的声音
It doesn't normally make noise, does it?
它自己又不会说话
Well, atomic hydrogen absorbs and emits radiation at certain frequencies:
其实 氢原子会以不同频率吸收和放出辐射
its atomic spectrum.
也就构成了它的原子光谱
And, if hydrogen emitted sound waves instead of light waves,
如果氢放出的不是光波而是声波
this is what it would sound like
你现在听到的就是氢的声音
(though I did pitch-shift it down so it would be audible to the human ear)
我把它降了个调 使人耳能听到
So, just like you might have seen false-color pictures of galaxies and planets
就像通过肉眼可见的颜色
made by shifting infrared or radio-wave images into the visible spectrum,
制作用红外线照的行星的假色图像
this is a false-pitch sound, shifted into the audible spectrum.
这也就是氢的假调声音
And it's what our eyes hear when they see this:
准确的说是我们看到下图时听到的声音
Enjoy
