In 2023, the ALICE experiment was ready for their best year yet, until a mysterious signal threatened everything. As the LHC wraps up its 2025 lead-ion run, physicists recall how they worked together ...

For more than two decades, amateur photographer Dale Carter has documented the physicists who come to the Black Hills for their research. Photography is sometimes thought of as one part skill and one ...

Scientists on the ATLAS experiment explored the polarization of W bosons to test the Higgs mechanism and gain a deeper understanding of the first moments after the Big Bang. After the Big Bang, the ...

LHCb’s discovery of proton-like particles behaving differently than their antimatter counterparts brings scientists one step closer to finding out why antimatter disappeared in the early universe.

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 ...

Once a year, the Large Hadron Collider smashes lead ions. But how do scientists get a heavy metal into a particle accelerator? Inside an ordinary-looking cupboard in an ordinary-looking office, ...

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.

The largest camera ever built for astrophysics has completed the long journey from SLAC National Accelerator Laboratory in California to the summit of Cerro Pachón in Chile. The 3200-megapixel LSST ...

In India, scientists are building a new LIGO detector, enhancing the capabilities of the observatory that reported the first observation of gravitational waves. In 2011, three physicists embarked upon ...

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, ...

In the 1900s, Albert Einstein unified the concepts of space and time, giving us a useful new way to picture the universe. At the start of the 20th century, physicists had a problem: The speed of light ...
