A new type of self-interacting dark matter could provide solutions to three very different cosmic puzzles, new research ...

A good chunk of cosmology is riding on whether dark matter exists or not. But what makes us so certain that dark matter is ...

Theories of quantum mechanics predict that some particles can exist in superpositions, which essentially means that they can be in more than one state at once. When a particle's state is measured, ...

Something invisible holds the universe intact. It outweighs everything you can see—every star, every gas cloud, every ...

A new kind of dark matter could help explain some of the universe’s mysteries, a new study suggests. The study proposes that there are dense clumps of “self-interacting dark matter”, or SIDM, each ...

A new study suggests that decaying dark matter may have helped create the universe’s first supermassive black holes much ...

In the chaotic first moments after the Big Bang, ripples in spacetime may have done more than just echo through the ...

Researchers have been looking at everything, including supernovas, trying to uncover the mysteries of dark matter. Recent scientific studies suggest that dark matter might not be a particle hiding in ...

Ask most astronomers, and they’ll tell you that dark matter and dark energy make up more than 95 percent of the universe and that they are the explanations for many of the large-scale phenomena we ...

In the standard model of cosmology, dark matter particles do not collide with themselves. Self-interacting dark matter can ...

"The dark structures shaping galaxies today could be relics from a time before the Big Bang." The post Physicist Proposes ...

Dark centre? A simulated version of the Milky Way galaxy. (Courtesy: AIP/ A. Khalatyan) Astronomers have long puzzled over the cause of a mysterious “glow” of very high energy gamma radiation ...
