[catalogued under 27. Natural Reality / B. Modern Physics / 3. Chromodynamics / a. Chromodynamics]

Full Idea

The strong force holds quarks together within protons and neutrons, and residual effects of the strong force bind protons (whch repel one another) and neutrons together in nuclei.

Gist of Idea

The strong force binds quarks tight, and the nucleus more weakly

A Reaction

So the force is much stronger between quarks (which can't escape), and only 'residual' in the nucleus, which must be why smashing nuclei open is fairly easy, but smashin protons open needs higher energies.
