The search for dark matter has been largely unsuccessful so far. But now, scientists think they know where to look for it.

Dark matter is believed to make up most of the matter in the universe, yet it has never been directly detected. One theory ...

Dark matter is an elusive type of matter that does not emit, absorb or reflect light, interacting very weakly with ordinary ...

A new theory suggests fusion reactors could help scientists search for axions, mysterious particles that may explain dark ...

Searches for dark matter particles have come up empty so far, driving theorists to get more creative with their ideas.

Axions are hypothetical light particles that could solve two different physics problems, as they could explain why some ...

Elusive dark matter particles may lurk deep within the heart of the sun, and researchers have discovered that we can use a detector buried in the Antarctic ice sheet to find them. Dark matter is the ...

Reactors designed to produce energy from the fusion of atoms could have an unexpected scientific side benefit.

Long tubes, strong magnets, and bright lasers. Is that all it takes to entice the shyest particles in the universe to reveal themselves? Physicists working on the ALPS II experiment certainly hope so, ...

The most sensitive search yet for the elusive particles that may make up dark matter has turned up nothing, putting stronger limits than ever on the ingredients of nature's invisible stuff. Dark ...

Physicists announced Wednesday that a particle detector on the International Space Station has possibly detected signals of dark matter. Though exciting, the new results are still uncertain, and ...

One of the biggest mysteries of the universe is why its expansion seems to be speeding up. Physicists have attributed it to a strange force called dark energy, but exactly how it works is largely ...
