In 1986, in the prestigious journal Physical Review Letters, it was stated that in addition to the four basic forces known until then in nature (gravitational, electromagnetic, weak nuclear and strong nuclear), there was a fifth. Initially evidence was accumulated in favor and against. To analyze them they met in the French village of Ars. The conclusion of those present is that there is no fifth force and if it exists it is very weak.

Therefore, we must continue with the usual four basic forces.
