Astrophysicists Build Realistic Virtual Universe

sciencehabit writes "In the most detailed effort yet, astrophysicists and cosmologists have modeled the evolution of the universe right down to the formation of individual galaxies. The results of the mammoth computer simulation neatly match multiple astronomical observations, ranging from the distribution of galaxies in massive galaxy clusters to the amounts of neutral hydrogen gas in galaxies large and small (abstract). The findings once again neatly confirm cosmologists' standard theory of the basic ingredients of the universe and how it evolved—a result that may disappoint researchers hoping for new puzzles to solve."

Cool! Where can I get one?

I wanted to get a dollhouse for the kiddies, but a universe is even better.

internal detection

the big question is are entities in the simulation able to detect it is a simulation.
