Strong interactions are one of the fundamental forces of nature that hold atomic nuclei together. Also known as the strong force, it is responsible for binding quarks together to form protons and neutrons. Some synonyms for the strong force include the strong nuclear force and the strong interaction. Some researchers refer to it as the color force, which reflects the way that quarks interact with each other. This powerful force is crucial for the stability of matter and the universe as we know it. While not as well-known as gravity or electromagnetism, the strong force plays a vital role in understanding the structure of the universe.
