With big outstanding questions and little hints of new physics, physicists are now rethinking some of their most fundamental ...

In a recent study, ALICE scientists measured the way that lead ions colliding in the LHC sometimes transform into gold and ...

A large and unexpected excess of top quark pairs has the physics community excited, but the interpretation is still up for debate. In 1995, Alexander Grohsjean cut out a story from the local German ...

The LHCb experiment at CERN has revealed a fundamental asymmetry in the behavior of particles called baryons. “The reason why it took longer to observe CP violation in baryons than in mesons is down ...

Writer Chetna Krishna follows CERN’s “coolest” transport, a test of a system to ship stored antimatter across the continent. I reach CERN’s Antimatter Factory at 8 a.m. sharp. I’m here at the ...

The Planck scale sets the universe’s minimum limit, beyond which the laws of physics break. In the late 1890s, physicist Max Planck proposed a set of units to simplify the expression of physics laws.

Physics may seem like its own world, but different sectors using machine learning are all part of the same universe. In 2017, Savannah Thais attended the NeurIPS machine-learning conference in Long ...

The US physics community dreams of building a muon collider. In the spring of 2022, Karri DiPetrillo was gearing up for the final step of the Snowmass particle physics community planning process. It ...

A professor at the University of Tennessee reimagines the way we teach STEM with a science-fiction story-based class. In the beginning, a spaceship called the Yggdrasil is sailing through the cosmos ...

Scientists on the ATLAS collaboration performed the highest-energy measurement of quantum entanglement. On the smallest level, the universe operates in such a bizarre way that even Albert Einstein had ...

Electromagnetism and the weak nuclear force are two distinct fundamental forces. That wasn’t always the case. How many fundamental forces are there in our universe? For particle physicists, answering ...

Scientists are championing a relatively new technique as a method to understand the structure of the early universe in three dimensions. With enough time and magnifying power, a telescope can gather ...
