"WIMPs are still the leading candidate for dark matter, but billions of dollars of experiments have been done, only getting ...

The particle in question, known as a sterile neutrino, was supposed to only interact with gravity and have zero interactions ...

Inside the Large Hadron Collider, protons slam together at nearly the speed of light, creating a brief fireball of quarks and ...

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

New research puts forward compelling new evidence that dark matter interacts with cosmic "ghost particles" called neutrinos.

The Standard Model of particles and interactions is remarkably successful for a theory everyone knows is missing big pieces. It accounts for the everyday stuff we know like protons, neutrons, ...

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.

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 ...

The Large Hadron Collider began smashing atoms together in 2009 and continues to throw up surprising insights into the fundamental building blocks of the universe. It’s via evidence from particle ...

Physicists are exploring whether hidden dimensions and the shape of space could help explain why fundamental particles have ...

An illustration conveying the idea of a space-based quantum internet, which would seem, like the hypothetical particle of a tachyon, to outpace light. An illustration ...
