In particle physics, the strong interaction (also called the strong force, strong nuclear force, nuclear strong force ) is one of the four fundamental interactions of nature, the others being electromagnetism, the weak interaction and gravitation. Beside being in small particles, it is about 100 times stronger than electromagnetism, which in turn is orders of magnitude stronger than the weak force interaction and gravitation. It ensures the stability of ordinary matter, in confining the elementary particles quarks into hadrons such as the proton and neutron, the largest components of the mass of ordinary matter. Furthermore, most of the mass-energy of a common proton or neutron is in the form of the strong force field energy; the individual quarks provide only about 1% of the mass-energy of a proton.If the strong force was weaker than it is, the chemical elements needed for life would not be stable, and we would not be here. If it were stronger, all the hydrogen in the universe would have been burned to helium in the Big Bang. As a result, there would be no long-lived stars like the sun, and no water. There would probably be no complicated chemistry in the universe, and we would not be here. So here’s one of the most important forces in nature, the superglue of the atomic level, which really is holding things together quite nicely. fromquarkstoquasars/the-strong-nuclear-force/ en.wikipedia.org/wiki/Strong_nuclear_force
