Astrophysicists simulate a Milky Way-like galaxy; Supercomputer experiment supports cosmological model of a 'cold dark matter' universe

After nine months of number-crunching on a powerful supercomputer, a beautiful spiral galaxy matching our own Milky Way emerged from a computer simulation of the physics involved in galaxy formation and evolution. The simulation solves a longstanding problem that had led some to question the prevailing cosmological model of the universe.
