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 ...

The consortium running the European Space Agency's (ESA) Euclid mission has published the most extensive simulation of the cosmos to date. The modeling was based on algorithms developed by UZH ...

Some massive black holes spend billions of years far from the centers of their galaxies. A new study says that these ...

May 20, 2026 — University of California San Diego Halıcıoğlu School of Data Science and Computing astrophysicist Mike Norman is driving a new generation of cosmology simulations that push precision ...

IntroductionIn this series, we are verifying the hypothesis that "the universe might be a simulation running on a giant ...

IntroductionMy reflections, which began with the image of the world presented by Big Bang cosmology and modern astrophysics, ...

Cosmological simulations have become indispensable tools for understanding the assembly of galaxies within the framework of a ΛCDM Universe. By numerically integrating the coupled equations of gravity ...

Cosmologist Francisco “Paco” Villaescusa-Navarro has a problem. “We are spending billions of dollars in ground and space telescopes to decipher the mysteries of the universe,” he explains, “but we are ...

A strategy borrowed from generative AI — train cheaply on the familiar, then fine-tune on the hard problem — can cut the number of expensive physics simulations needed by nearly a factor of ten. But a ...
