A New Look at an Old Physics Mystery: Could Neutrinos Be Their Own Antiparticles?

A fresh retelling of Ettore Majorana's 1937 idea is drawing attention to one of modern physics' most persistent questions: whether neutrinos could be particles that are also their own antiparticles.

Key Takeaways

A 1937 paper by Ettore Majorana proposed particles that are their own antiparticles.
Neutrinos are a leading candidate for that possibility.
