The Glueball: How a Decades-Old Physics Mystery Was Just Solved
After 15 years of painstaking research, a Chinese-led international team has confirmed the existence of the glueball — a particle made entirely of force. This historic breakthrough, hailed as a 'triumph' by physicists worldwide, validates a core prediction of quantum chromodynamics and could reshape our understanding of the fundamental forces of nature.

The Big Idea
A particle made entirely of force. Not quarks, not electrons, not any of the usual suspects that populate the subatomic zoo — just pure, unadulterated force clumped together into a fleeting speck of matter. It sounds like something a science fiction writer would dream up after a particularly vivid hallucination, but it's real. A Chinese-led international team of scientists has just presented the strongest evidence yet for the existence of the glueball, a mysterious particle that...
