Physicists have determined that most of the universe is dark matter -- invisible to us but affecting the universe anyway.

Astronomers have long puzzled over the cause of a mysterious “glow” of very high energy gamma radiation emanating from the ...

A new study casts doubt on the universe’s accelerating expansion, suggesting dark energy might be weakening over time.

The universe is expanding, and that expansion is accelerating. But what is causing that to happen? The leading hypothesis is a repellent force that astrophysicists refer to as “dark energy,” which ...

Dark matter may be invisible, but scientists are getting closer to understanding whether it follows the same rules as ...

The Universe hides many mysteries, and dark matter represents one of the greatest enigmas that scientists are trying to ...

Particle physics continues to probe the most fundamental constituents of matter while dark matter research seeks to illuminate the unseen mass that permeates our Universe. Recent efforts have ...

An experiment designed to hunt for ever elusive dark matter has returned some strange and exciting signals. The anomalies are probably not dark matter itself, but could be an indication that we’re on ...

Some people may worry about being bitten by a snake or spider, but have you ever considered what would happen if a small ...

Scientists talk about dark matter an awful lot for something they don’t actually understand very well. They say that it’s important — and that we wouldn’t have stars and galaxies without it — though ...

Physicists at Stanford University and SLAC have built a contraption they hope will detect dark matter, though exactly which theoretical particles they think they’ll find—hidden photons or little blips ...
