New research suggests that relic black holes from before the big bang may still shape galaxies today. These black holes could ...

In the extremely early universe, primordial black holes could acquire a "dark charge," giving them an unnaturally long lifetime. This makes them an interesting, if exotic, candidate for dark matter, ...

Dark matter makes up most of the mass in galaxies and galaxy clusters. In fact, scientists estimate that ordinary matter makes up only about 5% of the universe, while dark matter makes up about 27%.

Add Yahoo as a preferred source to see more of our stories on Google. If dark matter particles decay, then scientists could hunt for signs of this process, including X-ray or gamma-ray radiation or ...

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 ...

Ordinary matter – basically, anything other than dark matter – makes up about 15% of all matter. But half of it has long been missing. Powerful bursts of radio waves emanating from 69 locations in the ...

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.
