Challenge to Quantum Theory: Could 'Paraparticles' Exist in 3D?

For decades, physicists have believed that only two fundamental particles exist: bosons and fermions. This belief is largely based on the DHR theorem and its underlying assumptions. However, new research suggests the possibility of a third type of particle, called a 'paraparticle,' in three dimensions. These particles possess hidden internal states that change when particles swap places, but these changes disappear during measurement. This discovery challenges conventional quantum theory and opens new avenues for research in quantum computing and condensed matter physics.
