Scientists have discovered that quarks and gluons within protons are quantum entangled, challenging traditional views of proton structure. Using high-energy particle collisions at facilities like the Large Hadron Collider, researchers saw evidence of entanglement through the disorder or 'entropy' of particle paths post-collision. This disorder, akin to a 'messy room,' indicates a strong interaction producing many quark-antiquark pairs and gluons. Findings suggest maximal entanglement within protons, influencing our understanding of nuclear physics and potentially guiding research at the future Electron-Ion Collider.
