US EditionAstronomers carry out largest ever cosmological computer simulation
- The biggest-ever computer simulations have been performed by astronomers to study the evolution of the universe from the Big Bang. Virtual galaxies and clusters of galaxies are emerging in detail as the simulations progress. The goal is to compare the virtual universe with images from NASA's James Webb telescope and the European Space Agency's Euclid telescope.
- The COSMA 8 machine, with the power of 17,000 home PCs, was used for the simulations, and a new code was developed to distribute the massive workload. Previous simulations focused on cold dark matter, but astronomers now believe that ordinary matter and neutrinos need to be considered to understand the evolution of the universe.
- The study, published in the Monthly Notices of the Royal Astronomical Society, aims to answer whether the standard model of cosmology is flawed or if there are biases in observational data. It is a crucial moment for cosmology, and the super precise simulations of the universe should provide the answer.

Astronomers carry out largest ever cosmological computer simulation
An international team of astronomers has carried out what is believed to be the largest ever cosmological computer simulation, tracking not only dark but also ordinary matter (such as planets, stars and galaxies), giving us a glimpse into how our universe may have evolved.
