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 ...

For nearly a century, astronomers have watched galaxies spin and the universe expand in ways that visible matter alone cannot explain. The dominant answer has been dark matter, an unseen substance ...

Researchers using new simulations suggest that the Milky Way’s past collisions may have reshaped its dark matter core. This distorted structure could naturally explain the puzzling gamma-ray glow long ...

Add Yahoo as a preferred source to see more of our stories on Google. The Galactic Center Excess, shines in high-energy gamma rays that can’t be explained by ordinary astrophysical processes. Its ...

A quiet shift in the numbers behind the universe’s growth is pushing scientists toward a bold possibility. Two of the cosmos’ most elusive players, dark matter and neutrinos, may not be strangers ...

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 ...

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 ...

Researchers at the Department of Energy's Oak Ridge National Laboratory are helping to pave a path for the eventual discovery of dark matter. With new approaches to measurement in the quantum realm, ...

NASA's Hubble Space Telescope captures the magnificent starry population of the Coma Cluster of galaxies, one of the densest known galaxy collections in the universe — and where the effect of dark ...
