Strong Nuclear Force: The Power That Binds the Nucleus

The strong nuclear force is the most powerful of the four fundamental forces.
It binds quarks together inside protons and neutrons via gluons.
It also holds protons and neutrons tightly in the atomic nucleus.
Without it, the repulsion between positively charged protons would blow nuclei apart.
The strong force is incredibly short-ranged, acting only over about 1 femtometer (a millionth of a billionth of a meter).
Most of a proton’s mass comes from the energy of the strong force, not the quarks themselves.
The property of confinement ensures quarks can never exist alone.
It explains why atomic nuclei are stable and why stars can fuse elements.
The theory describing it, Quantum Chromodynamics (QCD), is a cornerstone of modern physics.
Without the strong force, there would be no atoms, no chemistry, and no life.
