It took nearly a year of high-powered number crunching on various supercomputers, but researchers from the University of California Santa Cruz campus and the Institute for Theoretical Physics in Zurich, Switzerland have finally produced a computer simulation of a galaxy that looks much like our own. That may not sound so huge at face value, but it actually is the first high-resolution simulation of its kind that has turned out a galaxy similar to the Milky Way, and it has rescued the prevailing "cold dark matter" cosmological model of how our disc galaxy formed from a good deal of doubt.
