strong force that holds atomic nuclei together. That is the source (through mass deficit) that creates the nuclear binding energy or nuclear glue that acts to oppose the electrostatic repulsion of the protons. You might be aware that the strong nuclear force, along with the weak nuclear force, the electromagnetic force, and gravity, are the four fundamental forces in the universe.
