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

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

The theorized unseen structure of spacetime could also explain of the outstanding questions about the accelerating expansion ...

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

Quantum theory and Einstein's theory of general relativity are two of the greatest successes in modern physics. Each works ...

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 ...

The rapid acceleration of the universe’s expansion continues to challenge our understanding of fundamental physics. Why the ...

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

Physicists have measured an extremely rare particle decay inside the world's largest atom smasher — a discovery that bolsters the leading model of particle physics and leaves little room for ...

Physicists at the University of Bayreuth are among the international pioneers of power functional theory. This new approach makes it possible for the first time to precisely describe the dynamics of ...

The Standard Model. What a dull name for the most accurate scientific theory known to human beings. More than a quarter of the Nobel Prizes in physics of the last century are direct inputs to or ...

Jason Bono was one of the researchers behind a major scientific moment — when tiny particles unexpectedly unraveled one of the most important and successful theories in physics. Bono, who earned his ...
