In a study published earlier this month in the Journal of Cosmology and Astroparticle Physics, cosmologists trained an AI neural network on simulations of ΛCDM—the standard model of cosmology ...

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 ...

An international research team led by Chinese scientists at the National Astronomical Observatories of the Chinese Academy of ...

We see countless stars and galaxies sparkling in the universe today, but how much matter is actually there? The question is simple enough — its answer, however, is turning out to be quite a ...

Dark matter halos are everywhere in the universe, yet no telescope can see them. These vast, invisible structures surround ...

For decades, one of the biggest questions in cosmology has remained frustratingly out of reach: what, if anything, existed ...

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 ...

As I mention often on this blog, I have a great interest in the universe—astrophysics, quantum mechanics, cosmology, all that stuff. With that, I’m no expert in any of it. I just enjoy reading and ...

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, ...

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