Researchers created a new supercomputer model, based on observational data and the "Lambda Cold Dark Matter" theory of the universe.
研究人员在观测数据和兰姆达冷暗物质模型的基础上构建了一个新的计算模型。
The CDM theory makes no predictions about exactly what the cold dark matter particles are, and one large weakness in the cold dark matter theory is that it is unclear what the dark matter consists of.
CDM理论不做预言关于确切地什么冷的神秘的物质微粒是，并且一个大弱点在冷的神秘的物质理论上是它是不明的什么神秘的物质包括。
I think it has a cool little message; that no matter how dark the cloud is above you or how cold the rain, there is hope that things will pass and stuff gets better.
我认为它表达了一条非常酷的信息，那就是无论你头上的乌云有多黑暗或雨有多冷，仍然会有一份希望：一切不如意都将过去，事情也会变得更好。
By listening for these telltale vibrations in the quiet of a cold crystal, the researchers running the experiment should be able to detect the presence of the passing dark matter.
而静寂、冰冷的晶体一有响动，也就透露了暗物质的行踪。研究者通过仔细聆听，应该能找到途经而过的暗物质。
So just like that, from looking at hydrogen, we can tell how cold our Universe's dark matter has to be. And that's how hydrogen teaches us the temperature of dark matter!
