In 1938, Italian physicist Ettore Majorana disappeared. While it is not known what exactly happened to him, he did leave behind the theoretical basis for a new type of particle; one that is its own antiparticle — the Majorana fermion. Today, Majorana fermions are one of many candidates for dark matter, the mysterious form of matter which makes up around 85% of the total matter in the universe. Knowing how Majorana fermions polarize and annihilate with each other can help focus experimental efforts to detect and better understand dark matter.
