I've been reading about the Dirac equation, and most authors eventually make some statement to the effect that the fact of spin and antiparticles falling out of the equation reflects a deep connection to the structure of spacetime. Is the implication that the math requires four particle states (or types, spin up/down, matter/antimatter) because there are four dimensions of spacetime? And that this tells us something important about the way the universe is constructed and is not just an artifact of the mathematics?(adsbygoogle = window.adsbygoogle || []).push({});
