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

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

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

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.

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.

"Dark photon" theory says light's interference patterns may emerge from quantum particles, not waves, upending centuries of ...

Paul M. Sutter is an astrophysicist at SUNY Stony Brook and the Flatiron Institute, host of "Ask a Spaceman" and "Space Radio," and author of "How to Die in Space." Sutter contributed this article to ...

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 ...

After a decade of painstaking measurements, scientists have delivered a major plot twist in particle physics: a long-hypothesized “mystery particle” likely doesn’t exist. Using the MicroBooNE ...
