Majorana's Paradox

Majorana's Paradox arises from the notion that if you could find a particle that is its own antiparticle, such as the hypothetical Majorana fermion, it would challenge our understanding of particle physics. In simple terms, this means that the particles that make up matter (like electrons) usually have a counterpart with opposite properties (their antiparticles). If a particle is identical to its antiparticle, it complicates our theories about the universe's structure, as it blurs the lines between matter and antimatter and raises questions about how we understand particle interactions and symmetries in physics.
