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

An analysis of several experiments aimed at detecting the mysterious neutrino has identified a hint of a crack in the ...

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.

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 ...

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

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 ...
