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 to solve the puzzle.
Among the 10,000 people from around the world who are working on the Large Hadron Collider, 1000 hail from universities and national labs in the United States.
They started out scanning the cosmos for signs of extraterrestrial intelligence with SETI@ home. They’ve plotted chess moves, battled malaria, and folded proteins, all from their home computers. Now, volunteers are tackling particle physics with LHC@home.
In the fall of 1997, I was leading the calibration and analysis of data gathered by the High-z Supernova Search Team, one of two teams of scientists the other was the Supernova Cosmology Projecttrying to determine the fate of our universe: Will it expand forever, or will it halt and contract, r
As Clark Cully watched the movie Déjà Vu with his parents, something about the movie’s time machine—with its bright blue wedges of metal spewing a ring of wires—seemed eerily familiar.
The next big experiment in particle physics won’t need an accelerator, detector, or other big machine. It doesn’t even involve subatomic particles—unless you count the electrons that flow through electronic circuits, carrying bits of information from one human brain to the next.
