One such particle is called an axion.

这种粒子叫做轴粒子。

An axion would pass right through you like you weren't there.

轴粒子会穿过你，就像你不在那里一样。

Oh, I see you came around to my idea for distinguishing massive particles from axion particles.

看来你转而支持我的想法了，关于如何区分大质量粒子和轴子。

(Laughter) And whoever chose " the axion" just completely blew it, OK?

（笑声） 谁选择了“轴子”，谁就完全搞砸了，好吗？

So how are we going to go looking for the axion or any other dark matter particle?

那么我们如何去寻找轴子或任何其他暗物质粒子呢？

(Laughter) If it's not an axion, you better fix that.

（笑声） 如果它不是轴子，你最好把它修好。

Well, in the case of the axion, it helps to pay attention to its quantum classification.

好吧，就轴子而言，关注它的量子分类是有帮助的。

I'm completely enamored with the idea of axion Bose-Einstein condensates.

我完全迷恋轴子玻色-爱因斯坦凝聚态的想法。

It's an axion condensate orbiting a central mass.

它是围绕中心质量运行的轴子凝聚体。

If dark matter were made of axions, then clouds of it could be enveloping clusters of galaxies and we'd never see them.

如果暗物质是由轴粒子构成的，那么它的云团就可能包围着星系团，而我们永远也看不到它们。
