Physicists believe they have discovered a particle that is both matter and anti-matter, an idea that was first theorised 80 years ago.

 

When the Big Bang created the universe out of nothing, scientists believe the explosion created equal amounts of matter and anti-matter.

 

And, if they were ever to meet, they would annihilate each other – returning to ‘nothing’ apart from a burst of energy.

 

However, in 1937 an Italian theoretical physicist, Ettore Majorana, predicted the existence of a strange class of particles called fermions that were their own anti-particles.

For decades physicists have sought signs of misbehaving particles—evidence of subtle cracks in the “Standard Model” of particle physics, the dominant theory describing the most fundamental building blocks of our universe. Although the Standard Model has proved strikingly accurate, scientists have long known some adjustments will be needed. Now, as a recent review paper in Nature documents, experimenters have started seeing suggestions of particles flouting the theory—but they’re not quite the violations theorists were looking for.
