Predicted by the <Dirac equation>.

Can be easily seen from the solution of <equation Expanded Dirac equation in Planck units> when the particle is at rest as shown at <video Quantum Mechanics 12b - Dirac Equation II by ViaScience (2015)>.


Antimatter

Change sign if you swap two input values.

Can only exist in <2D> surfaces, not 3D, where <fermions> and <bosons> are the only options.
