TL;DR
Ever wondered what happens when you flip E = mc² in quantum physics? Veritasium walks you through how Paul Dirac’s bold notion of negative energy exposed cracks in Schrödinger’s equation and led him to the now-famous Dirac equation—predicting the existence of anti-electrons (positrons) and hinting at a whole anti-universe.
Along the way, you’ll meet “the strangest man in physics,” wrestle with the Klein–Gordon equation, Heisenberg’s uncertainty, and the mind-bending idea that antiparticles are just electrons traveling backward in time. Packed with historical tidbits, expert insights (Farmelo, Vafa), and museum-grade archives from FSU and Caltech, it’s a wild ride from math oddity to the discovery of antimatter.
