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 ...

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 ...

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 ...

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 ...

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 ...

"Dark matter can be red hot when it is born, but still have time to cool down before galaxies begin to form." When you purchase through links on our site, we may earn an affiliate commission. Here’s ...

Astrophysicists and cosmologists at the University of California, Santa Cruz, are among the first scientists to have access to the powerful new Columbia supercomputer at the NASA Ames Research Center.

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 ...
