The matter that makes up the universe consists of particles such as electrons and protons, as well as their counterparts known as antiparticles. Particles and antiparticles that collide, however, annihilate each other in an intense flash of energy. Nevertheless, the Italian physicist Ettore Majorana proposed that some particles could exist that are their own antiparticles although physicists are yet to observe such particles.
