Quarks are fundamental particles thought to be permanently confined within protons, neutrons, and other composite particles. Quantum Chromodynamics (QCD) theory suggests that separating quarks requires immense energy, increasing confinement rather than allowing separation. While strong evidence supports that quarks are bound this way, absolute proof is still elusive. If quark confinement were ever disproven, it would challenge our understanding of particle physics. #Quarks #QCD #ParticlePhysics
