구속론, or the theory of confinement, is a concept in physics that explains how certain particles, such as 쿼크 and 글루온, are held together within 핵 and 입자. This theory is essential for understanding the strong force, one of the four fundamental forces in nature, which governs the interactions between these particles. The theory of confinement suggests that quarks cannot exist independently; they are always found in groups, forming larger particles like 프로톤 and 중성자. This phenomenon is crucial for the stability of atomic nuclei and helps explain the structure of matter in the universe.
