With big outstanding questions and little hints of new physics, physicists are now rethinking some of their most fundamental assumptions. For centuries, scientists thought the universe was filled with ...

NSF–DOE Vera C. Rubin Observatory is gearing up to illuminate the universe’s darkest secrets with groundbreaking new technology. Three decades ago, physicist Tony Tyson sat in the control room of the ...

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 ...

Documenting the work of building the world’s largest neutrino experiment presents photographers with a unique set of challenges. Discussing her decades-spanning career, photographer Annie Leibovitz ...

The CMS experiment is developing a new type of trigger that looks for anomalies. As far back as he can remember, Abhijith Gandrakota has felt a natural pull toward physics. “For me, it’s a fundamental ...

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 ...

An advisory committee recommends the US work to advance three key areas of emerging accelerator technology. To study some of the smallest things in the universe, particle physicists use some of the ...

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 ...

The ATLAS collaboration recently measured the strength of the strong force to a record level of precision, but there’s still a long way to go toward understanding this fundamental force. In September, ...

Results from the ALPHA experiment confirm that matter and antimatter react to gravity in a similar way. Danielle Hodgkinson watched with cautious curiosity as the data poured onto screens in the ...
