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 ...

Composing some 85% of the universe's total mass, dark matter betrays its presence only through gravity, unlike ordinary ...

Scientists still don’t know what dark matter is. It doesn’t interact with any electromagnetic force or regular matter except through the gravitational force it exerts. A research team has a come up ...

A new paper published in Physical Review Letters reveals that a leading dark matter candidate—the hypothetical "dark ...

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 ...

Astronomers have discovered that the jet of a distant blazar has been gravitationally lensed by an unseen source of dark ...

Hypothetical particles called axions have been sought by physicists for decades, as they are the leading candidate for what makes up dark matter. But we may not need new experiments to find exotic ...

Previous claims that dark matter had been detected are being called into doubt now that a powerful new experiment has failed to see any of the elusive particles. For years, scientists running the DAMA ...

A study by Dartmouth researchers proposes a new theory about the origin of dark matter, the mysterious and invisible substance thought to give the universe its shape and structure. The researchers ...
