Dark matter, one of the Universe’s greatest mysteries, may have been born blazing hot instead of cold and sluggish as ...

Computer simulations by astronomers support the idea that dark matter -- matter that no one has yet directly detected but which many physicists think must be there to explain several aspects of the ...

A cosmological simulation study by researchers from the Shanghai Astronomical Observatory of the Chinese Academy of Sciences has systematically revealed, for the first time, how the interaction ...

Galaxies are far more than the sum of their stars. Long before stars even formed, dark matter clumped up and drew regular matter together with its gravity, providing the invisible scaffolding upon ...

Computer simulations designed and run by researchers at the University of California-Irvine suggest that dark matter does in fact exist and is a central part of explaining how the universe works. The ...

If a new research paper’s theory is correct, then there should be a much higher population of very small, very luminous galaxies in the early universe. With everything we learn about the nature of ...

The Milky Way is part of a billion-light-year-wide structure called the Supergalactic Plane, but we don’t exactly fit in. Most of the galaxies in the Supergalactic Plane are messy elliptical blobs. In ...

In simulations, scientists modeled how our universe would operate if dark matter was cold and slow versus if it was hot or warm and fast. They showed that with cold dark matter, the universe’s ...

Astronomers report that the Champagne Cluster is actually two galaxy clusters in the process of merging, based on X-ray, optical, and spectroscopic observations published in 2025 ...

Researchers at Perimeter Institute are now delving deeper into how a specific dark matter candidate, known as self-interacting dark matter (SIDM), might shape the evolution of cosmic structures. The ...

This is interesting of course, but the article suffers from problems. Besides the missing article link, the linked spiral arm dynamical mass excess observations are not explained by dark matter as it ...
