Astronomers found evidence that dark matter and neutrinos may interact, hinting at a "fundamental breakthrough" that ...

Dark matter seems invisible, but it makes up most matter, and we have evidence that it gives the cosmos its shape. Now ...

Frank Close tells us about the history of particle physics, and what it means that charge in our universe's matter is so closely balanced. When you purchase through links on our site, we may earn an ...

Columnist Natalie Wolchover checks in with particle physicists more than a decade after the field entered a profound crisis.

UC Santa Cruz physicist Stefano Profumo has put forward two imaginative but scientifically grounded theories that may help solve one of the biggest mysteries in physics: the origin of dark matter. In ...

Physicists at CERN have reported the first observations of matter-antimatter imbalance in a subatomic particle 'baryon', offering clues as to why matter dominates in the universe. Particles of ...

On Wednesday (Sept. 27) morning, an international team of physicists reported a major finding about an elusive form of matter known as antimatter. It appears that antimatter responds to gravity the ...

Everything we see around us, from the ground beneath our feet to the most remote galaxies, is made of matter. For scientists, that has long posed a problem: According to physicists’ best current ...

In recent years, a curious hypothetical particle called the axion, invented to address challenging problems with the strong nuclear force, has emerged as a leading candidate to explain dark matter.

The universe's matter-antimatter asymmetry, where matter significantly outweighs antimatter despite their theoretically equal creation at the Big Bang, remains a major unsolved problem in physics.
