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

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

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.

New research from the University of Sheffield provides compelling evidence that dark matter and neutrinos may interact, challenging the long-standing ...

Physicists have spent decades treating mass as something the universe simply hands to particles, a property encoded in ...

Scientists at CERN’s Large Hadron Collider (LHC) have for the first time observed a fundamental asymmetry in the behavior of baryons, the particles that form the bulk of all visible matter. The ...
