Far from an austere backwater, the intergalactic medium (IGM) is turning out to be the central staging area for cosmic evolution.

星系际介质(igm)完全不是死水一潭，它正跃居宇宙演化的中心舞台。

Their new model reproduces 13 billion years? Worth of cosmic evolution, resulting in a surprisingly accurate tally of the different kinds of galaxies we see.

他们的新模型再现了130亿年的宇宙演化史，得到的结果与我们今天所看到的各种不同星系惊人的吻合。

The survey is some 100 times larger than the previous largest map of the web of dark matter, gathered by the Hubble telescope's Cosmic Evolution Survey, or Cosmos.

Dr Massey and his colleagues were able to map the matter (both dark and visible) in the bit of the firmament covered by the Cosmic Evolution Survey by looking for characteristic distortions in the shape of distant galaxies that only Hubble, which is beyond the image-blurring effects of the atmosphere, can see.
