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

The mysterious substance that binds galaxies together could naturally be "in tune" with a hidden fifth dimension, according ...

A new theoretical framework suggests dark matter’s elusive behavior may arise from the geometry of a hidden fifth dimension.

Dark matter may not have needed a calm, cold start to help build the universe. That is the challenge raised by new work from researchers at the University of Minnesota Twin Cities and Université ...

A new study proposes dark matter resides in a hidden extra dimension. This hidden dimension may naturally align particle ...

Dark matter is already one of the strangest substances in the universe, but a new study suggests this elusive material could ...

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 ...

The Bullet Cluster of galaxies might only have half as much dark matter than scientists thought, or perhaps even none at all, ...

A ghostly ring of dark matter captured by the Hubble Space Telescope. Galaxies, including the one we call home, are within halos of dark matter. But what exactly dark matter is remains something of a ...

UC Santa Cruz physicist Stefano Profumo has put forward two imaginative but scientifically grounded theories that may help solve one of the biggest mysteries in physics: the origin of dark matter. In ...

The phenomenology of dark matter in particle physics addresses the bridge between theoretical models of unseen matter and the experimental or observational signatures that might reveal its nature.
