Physicists have long struggled to unite quantum mechanics—the theory governing tiny particles—with Einstein’s theory of ...

For over a decade, confusion over the size of the proton has held scientists back. Disagreeing measurements of the subatomic particle’s radius meant that scientists couldn’t test one of their key ...

The Sun unleashes a torrent of charged particles. Some of them slam into the Earth’s atmosphere, triggering breathtaking auroras in the night sky. But for equipment that’s orbiting our planet in outer ...

Physicists have discovered a surprising new “Island of Inversion” in a place no one expected: among nuclei where the number ...

Particle never before seen on Earth detected; it could come from a primordial black hole and the origin of the universe.

As foretold, the Relativistic Heavy Ion Collider—among the most powerful heavy-ion colliders in the world, second only to CERN’s LHC—ran its final particles and ceased operations last Friday. This is ...

Nobel laureate Dr. James Peebles will discuss the still-unanswered questions regarding the expansion of the universe, dark matter and more. We have good evidence that the universe we see around us is ...

Scientists discovered “magic” top quarks at CERN’s Large Hadron Collider, demonstrating how the facility has evolved to support quantum computing research. Researchers at ATLAS observed ...

A surprising and rare particle decay has left scientists puzzled as kaons, particles made up of quarks, are decaying in ways that defy current physics models. Could this anomaly indicate the existence ...

When you drill down into the very fabric of reality—where elementary particles make up the matter that is you and me and everything around us in three-dimensional space—things get divided nicely into ...

Particle physics is using ever more interdisciplinary means to seek ever more exotic phenomena, Robert P Crease finds, but ...
