Thank you Jack !!jacmac wrote: I suggest that Wilhelm Weber(1804-1891) supports the ideas of Bengt Nyman.
Weber’s determination of a minimal distance below
which the Coulomb force, the repulsion of
like particles, must reverse and become attractive.
Thus the strong force comes from the natural repulsive force of like charged particles, that attract at VERY CLOSE distances, according to Weber.

Weber is and was completely right. In Webers days we did not know about quarks (1945). This made the force reversal somewhat of a mystery.
Today quarks, simple geometry and Coulomb's law resolves the question. Two protons, each consisting of 2 positive and 1 negative quark can position themselves in such a way that the two positive quarks in one proton huddle the one negative quark in the second proton. Distances between them become so short that this intense double attraction outweighs the remaining four repulsive forces between the four positive quarks trying to push the two protons apart.
If you force these two protons apart by just a short distance, the 1/r^2 differential diminishes and the two protons repel each other.
Again, thank you Jack.
