The Standard Model is an "astoundingly successful" theory in particle physics, detailing the behavior and interactions of 17 fundamental particles (12 fermions and 5 bosons), with thousands of precise ...

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

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

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, ...

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

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.

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 ...

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 ...

The original version of this story appeared in Quanta Magazine. When it comes to understanding the fabric of the universe, most of what scientists think exists is consigned to a dark, murky domain.

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 ...
