Cosmologists are finally beginning to sketch a coherent picture of the universe we cannot see, using exquisitely detailed ...

With contributions from Brown faculty and students, the LUX-ZEPLIN experiment analyzed the largest dataset ever collected by a dark matter detector, and the results provide the strongest constraints ...

By studying tiny distortions in the shapes of distant galaxies, scientists mapped dark matter and dark energy across one of the largest sky surveys ever assembled. Their results back the standard ...

There are a growing number of hints that the universe might not have evolved in the way that cosmologists thought. If those hints are confirmed by new sky surveys, it might turn out that dark matter ...

"The new model can account for both structure formation and stability, and the key observational properties of the expansion of the universe at large." When you purchase through links on our site, we ...

In a new study, scientists began pondering a pretty wild question: What if black holes can convert dead star matter into dark energy, the mystery force driving the acceleration of the expansion of the ...

Because dark matter is completely invisible to light, science had to look for clever new methods to spot it.

Only 31 percent of the universe is made up of matter, scientists have discovered, with the rest being made up of dark energy. Previous models and observations of the universe have estimated that the ...

A new theory claims dark matter and dark energy don’t exist — they’re just side effects of the universe’s changing forces. By rethinking gravity and cosmic timelines, it could rewrite our ...

Dark energy makes up about 70% of the universe and causes its expansion to accelerate. It's different from dark matter; dark energy pushes space apart, while dark matter pulls things together. We ...

By studying faint distortions in galaxy shapes across a vast region of sky, scientists probed the hidden structure of the universe. In the standard picture of the universe, nearly everything is hidden ...
