In September 2024, physicists made a discovery at CERN that could change how we understand the universe. For the first time, scientists saw quantum entanglement, the mysterious link between particles, ...

In a never-before-seen particle, four quarks of a feather flock together. Physicists think they have detected the first conglomerate of four quarks incorporating more than two of the same kind. This ...

Quarks are elemental particles, with no sub-structure. Understanding them is crucial to learning how physics works on the smallest levels. By studying collisions of incredibly small particles made up ...

Data galore: a simulation of the particle tracks produced when a Higgs boson is created in proton–proton collisions at the LHC. (Courtesy: CERN) An international collaboration is exploring how quantum ...

The Large Hadron Collider (LHC) sparked worldwide excitement in March as particle physicists reported tantalizing evidence for new physics — potentially a new force of nature. Now, our new result, yet ...

The particles that are in an atom: protons, neutrons and electrons The particles that are in protons and neutrons: quarks The four fundamental forces: gravity, electromagnetism, the strong force and ...
