strong force mystery

[AntonioLao]

The strongest force in the universe is no doubt the strong color force of the gluons. However, the strengths of these forces remain a mystery to this day. These are its variations between being repulsive, attractive, and effective.

The strong force is practically zero for distances greater than 3 fermis (1 fermi is 10^{-15} meter). Between the distances of three and above 0.5 fermis, it is attractive with absolute maximum energy potential of 100 MeV; at lesser distance, it is repulsive with energy potential toward positive infinity. At about .64 fermis, the strong force is identically zero at a singular point of spacetime. Comparing this to Planck length of 10^{-35} meter, the difference is 20 orders of magnitude or 1 meter to 100,000,000,000,000,000,000 meters or a distance of 10 light-years.
