Dark energy is a mystery so daunting that it stretches and strains our most robust theories. The universe is expanding, driven by the unknown force that we've named Dark Energy. Dark Energy is also ...

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 ...

Milky Way disk flip simulations from Durham University's NAM 2026 presentation show the Milky Way's galactic disk flipped more than 90 degrees after a head-on collision with the Gaia-Sausage-Enceladus ...

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 ...

Chinese scientists and international collaborators have used one of the largest cosmological simulations ever created to "fast-forward" the universe from the Big Bang to the present day inside a ...

An international research team led by Chinese scientists unveiled the first batch of findings of the largest-ever cosmological simulation to date, codenamed "HyperMillenium," on Thursday. Such ...

The research team is led by Carnegie Mellon University and includes scientists from the Harvard-Smithsonian Center for Astrophysics and the Max Planck Institute for Astrophysics in Germany. The ...

Cosmological simulations of dark matter halos form the backbone of our understanding of large-scale structure in the Universe. By numerically evolving millions to billions of particles under gravity, ...

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 ...

Some of the hardest questions in cosmology begin where the usual math gives up. Push Einstein’s theory far enough back toward ...
