Capturing the full sweep of observable space and time, the largest cosmological simulation to date shows how gravity could have gathered ripples left by the big bang into the colossal structures--walls, clumps, and filaments of galaxies--that fill the visible universe. The result is a coarse-grained look at cosmic history within a cube 10 billion light-years on a side, a volume so big that if Earth sat in one corner, the far corner would hold some of the most distant galaxies and quasars ever seen. Other cosmologists expect this model universe to be a powerful tool for interpreting data from large surveys of the real sky.
