So why should I care? And moreover, how can something as mundane as this super-simple atom emitting and absorbing light teach me anything about dark matter?!
那么，我干嘛要关心呢？此外，氢原子吸收与辐射光线这些超级简单的玩意能告诉我关于暗物质的什么信息呢？
Massive objects like the sun can bend light, but colossal clouds of dark matter create "bubbles" in the cosmos that magnify, distort and duplicate the light of galaxies or stars behind them.
巨大的星体，例如太阳能够使光弯曲，但是庞大的暗物质云会产生宇宙“气泡”，由星系或星体发出的光经过这些“气泡”会被放大，扭曲和复制。
As I said earlier, dark matter doesn't emit, absorb, or reflect any type of light.
正如我前面所说，暗物质不会发射、吸收或反射任何形式的光波。
A bit like life itself, perhaps? No matter how dark our problems, there's always a clink of light to encourage us to keep on.
或许有点像生活本身？无论路途又多么艰辛，总会有一道光满激励我们继续前行。
The dark matter makes up most of the total mass, and dominates the gravitational lensing of the cluster, or the bending of light from background galaxies due to gravity.
暗物质构成了大部分的总质量，并主宰了集群的引力透镜，或从光线弯曲的背景星系因引力。
Do not cry, when you observe that, as a matter of fear of the dark, you know, it certainly is light behind.
不要哭，当你发现前面是令人恐惧的黑暗时，你要知道，它后面一定就是光明。
Dark matter is the term for matter which cannot be detected directly, because it does not emit or reflect light or radiation - or, at least, not enough to be detected by our present sensors.
暗物质是一种人类不能直接观察到的物质，因为它既不反射也不释放光线或放射线——至少，我们现有的探测器无法观测到它。
Some natural matter can glow with light in the dark.
一些自然物质在黑暗中可以发光。
Scientists have so far been unable to directly observe dark matter, and have only been able to detect it by measuring its gravitational effect on light.
到目前为止，科学家们还不能够直接观察到暗物质，他们只有通过观测对光线所造成的引力影响，才能够发觉暗物质的存在。

里面统一了超光速、黑洞、白洞、暗物质、暗能量等知识，形成了一种比较合理的宇宙描述。
Those damaged cells by dark matter energy of light have restored their activeness. Not only so, those cells itself also seems to have some radioactive mutation, changed to strong.
那些被暗物质光能摧毁而完全失去活性的细胞完全恢复了正常，不但如此，那些细胞本身似乎还发生了一些放射性突变，变得强壮了。
No matter how dark our problems, there's always a clink of light to encourage us to keep on.
无论路途有多么艰辛，总会有一道光芒激励我们继续前进！
Comparing the calculated mass and the total mass of the light-emitting galaxies in the galaxy cluster would determine the amount of dark matter that exists in the galaxy cluster.
把计算出的质量和星系团中发光星系的总质量相比较，就能确定出星系团中存在多少暗物质。
