Our universe contains an astonishing array of visible structures ranging in size from planets, to stars, to galaxies and clusters of galaxies. We can also look to great distances, and hence back in time, and see the early, chaotic progenitors of current structure. Eventually, at the furthest distances we see just the small ripples in the afterglow of the Big Bang that are the seeds for all current structure. How did this evolution happen? This project puts the universe into a computer, allowing us to experiment with how cosmic structures form, interact and evolve; in hours or days we can model what has taken 14 billion years of cosmic history.

我们的宇宙包含一个令人惊讶的可见结构，从行星到恒星，星系和星系簇不等。我们还可以看待很大的距离，从而回到了及时，并看到当前结构的早期，混乱的祖细胞。最终，在最远的距离处，我们看到了大爆炸余潮中的小涟漪，这是所有当前结构的种子。这种进化是如何发生的？该项目使宇宙进入计算机，使我们能够尝试宇宙结构的形成，相互作用和发展。在几个小时或几天内，我们可以建模花费了140亿年的宇宙历史。
