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 ...

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 ...

If dark matter is made from "dark" versions of the basic building blocks of ordinary matter, the world's largest particle accelerator should be able to pin it down, a new study suggests. When you ...

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 ...

Neutrinos are one of the most elusive and omnipresent particles in the universe. Their strange properties may explain why the amounts of matter and antimatter in our universe aren’t equal, as most ...

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 ...

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

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.
