If dark matter particles decay, then scientists could hunt for signs of this process, including X-ray or gamma-ray radiation or even emitted "ghost particle" neutrinos, in vast clusters of galaxies.

The universe is mostly a ghost story we don’t understand. Everything we know of, the stars, the planets, and everything on ...

Why didn’t the universe annihilate itself moments after the big bang? A new finding at Cern on the French-Swiss border brings us closer to answering this fundamental question about why matter ...

Dark matter keeps getting blamed for the universe’s big patterns while staying stubbornly out of reach. You cannot see it, touch it, or capture it. Yet its gravity helps shape galaxies, and that makes ...

Few things in the universe are as perplexing as dark matter — the invisible and exotic “stuff” that is thought to make up most of the matter in galaxies. The theory goes like this: To reconcile our ...

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, ...
