A new method simulates the universe 1000 times faster

Cosmologists love universe simulations. Even models covering hundreds of millions of light years can be useful for understanding fundamental aspects of cosmology and the early universe. There's just one problem--they're extremely computationally intensive. A 500-million-light-year swath of the universe could take more than three weeks to simulate. Now, scientists led by Yin Li at the Flatiron Institute have developed a way to run these cosmically huge models 1000 times faster. That 500-million-y...
