Pion is the particle that explains why atoms don’t explode

If opposite charges attract and like charges repel… How can the protons that make up the atomic nucleus, be so together and not shoot back due to repulsion?

This question was more than repeated in the first third of the 20th century. The scientific community could not understand what was hidden behind the fact that the atomic nucleus did not explode. Was it power? Field? A particle they didn’t know about yet? The answer to this question was given in 1930 by the Japanese physicist Hiseki Yukawa: the solution was peonies.

WHAT ARE PEONIES?

By pions we know a special type of subatomic particle known as a meson. To better understand what they are and how they work, we need to think of pions as small building blocks made up of even smaller components called quarks. These are very light particles with a mass of about 270 times less than that of a proton. In addition, they are very unstable: their half-life is only 26,033 nanosecondsThis means that after this short time, most of them will decay into other particles. In fact, this process typically produces a muon, another subatomic particle, and a muon neutrino, an even smaller and harder-to-detect particle.
