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 ...

The Classic Story of Star Birth Gets a Shake-Up For billions of years within the Milky Way (but not during the first few ...

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 ...

The Milky Way may not always have faced the same direction. New simulations suggest its stellar disc could have swung through ...

Dark matter appears to hold galaxies together, yet it has never shown itself directly. A new theory suggests the missing ...

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 ...

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, ...

With less than 20 percent of all physical matter made from visible stuff—from stars and planets, to the kitchen sink—astronomers continue to hypothesize what form the invisible majority of the ...

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 ...

Irvine, Calif., April 29, 2024 — 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 ...

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 ...
