Quick Summary

Asymptotic freedom is a phenomenon in physics, specifically within the study of the strong force. It describes the behavior of quarks, the fundamental particles that make up protons and neutrons. Contrary to forces like gravity or electromagnetism, the attraction between quarks decreases as they get closer to each other. This counterintuitive behavior means that at very short distances, quarks act almost like independent particles. The strong force, which binds quarks together, is mediated by particles called gluons. This property is a key aspect of quantum chromodynamics, the theory describing these interactions.12
