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

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

A student-led experiment has shown that the search for dark matter doesn’t always require massive infrastructure.

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

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

One of the biggest mysteries in astrophysics today is that the forces in galaxies do not seem to add up. Galaxies rotate much faster than predicted by applying Newton’s law of gravity to their visible ...

Do constants of nature—the numbers that determine how things behave, like the speed of light—change over time as the universe expands? Does light get a little tired traveling vast cosmic distances? It ...

Add Yahoo as a preferred source to see more of our stories on Google. DESI has made the largest 3D map of our universe. The Earth is at the central vertex, and every ...

Transformative discoveries in cosmology are unfolding at Princeton as researchers explore the universe’s large-scale structure, including galaxies, dark matter, and dark energy. Professor of ...

Imagine a star powered not by nuclear fusion, but by one of the universe’s greatest mysteries—dark matter. Scientists have proposed the existence of “dark dwarfs,” strange glowing objects potentially ...

Celestial objects known as dark dwarfs may be hiding at the center of our galaxy and could offer key clues to uncover the nature of one of the most mysterious and fundamental phenomena in contemporary ...

New research suggests that relic black holes from before the big bang may still shape galaxies today. These black holes could explain dark matter, one of the biggest unsolved questions in cosmology.
