Clusters of galaxies also clump together to form superclusters, the largest structures in the Universe.

星系团也聚集在一起形成超星系团——宇宙中最大的结构体。

Where it wandered, among a cluster of galaxies, before settling into a new home in NGC 1277.

黑洞在星系团之间游走，之后在新家 NGC 1277 中安顿下来。

A billion years to pull apart clusters of galaxies, then hundreds of millions of years to pull apart galaxies themselves.

十亿年时间来撕裂星系群，然后是数亿年时间撕裂星系本身。

You can have clusters of galaxies that have hundreds to thousands galaxies in them. These clusters of galaxies are still bound to each other.

你能看到星系簇中有数百至数千个星系。星系簇始终能让星系束缚在一起。

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。

Then galaxies and clusters of galaxies.

然后是星系和星系团。

Clusters of galaxies arranged along filaments, like the Pisces-Cetus Supercluster Complex.

星系团沿着细丝排列，例如双鱼座-鲸鱼座超星系团。

And then over the course of billions of years, these density differences grew up to become clusters of galaxies in the great cosmic void.

然后在数十亿年的过程中，这些密度差异成长为巨大宇宙虚无中的星系团。

The Chandra X-ray Observatory has thus far made some detailed measurements about how dark matter must be distributed across a large cluster of galaxies.

到目前为止，钱德拉x射线天文台已经对暗物质该如何在一个大的星系团中分布进行了详细的测量。

Eventually, those teeny little bumps from the beginning of the Universe became galaxies and clusters of galaxies, now tens of billions of light years away.

最终，这些宇宙开始时的微小碰撞变成了星系和星系团，现在距我们有数百亿光年之遥。

It's this gravitational effect that makes galaxies spin at the rates they do and clusters of galaxies to hold together.

正是这种引力效应使星系以它们的速度旋转并使星系团聚集在一起。

The large scale structures of the universe, clusters of galaxies and galactic voids were seeded by quantum physics in the deep past.

宇宙的大尺度结构、星系团和星系空洞都是由遥远的过去量子物理学播下的种子。
