Majorana neutrino

A Majorana neutrino is a hypothetical type of particle that is thought to be its own antiparticle. In simpler terms, while most particles have distinct counterparts called antiparticles, a Majorana neutrino would not have a different opposite. This concept is significant in particle physics and has implications for our understanding of the universe, especially in theories related to dark matter and the nature of neutrinos, which are elusive particles that play a role in nuclear reactions and cosmic events. Their existence could help explain some unresolved questions in physics.
