When was the strong nuclear force first proposed?
Quick Answer
It was proposed in the early 1930s, soon after the discovery of the neutron.
The Full Story
The strong nuclear force was proposed in the early 1930s to explain why atomic nuclei hold together despite the repulsion between protons. After James Chadwick discovered the neutron in 1932, physicists such as Hideki Yukawa suggested that a short-range force must bind nucleons inside the nucleus. Yukawa's meson theory, proposed in 1935, became an important early explanation. This work marked a major step toward modern particle physics.
