Computational astrophysicists describe a new method for acquiring information on experiments using laser beams to reproduce cosmic conditions. Credit: Lawrence Livermore National Laboratory The development of ultra-intense lasers delivering the same power as the entire U.S. power grid has enabled the study of cosmic phenomena such as supernovae and black […]
