(Simons Foundation) Using a bit of machine learning magic, astrophysicists can now simulate vast, complex universes in a thousandth of the time it takes with conventional methods. The new method upscales low-resolution models to generate ‘super-resolution’ simulations. The process is akin to taking a blurry photograph and adding the missing details back in, making it sharp and clear, the researchers report in Proceedings of the National Academy of Sciences.
