A group of researchers has discovered proof for a strange particle that, strangely, is also its own antiparticle. It was first proposed 80 years ago but now existence of it might be a reality. The results, published in the journal Science , were led by researchers from Stanford University in California and the University of California. The notion of a particle having its own antiparticle was first introduced in 1937 when Italian physicist Ettore Majorana (who strangely disappeared in 1938) first suggested the theory. He said that inside the class of fermions, which comprise protons, electrons, and neutrons, some particles must have their own antiparticles, which became known as Majorana particles. An antiparticle is a particle that has the same mass as the normal particle, but a reverse electric or magnetic property. For instance, the electron’s antiparticle is the positron. If the two come across each other, they annihilate each other. In this study, the group of physicists stacke
