Veritasium’s latest video takes you on a whirlwind tour of Paul Dirac’s wildest predictions—from wrestling with negative-energy solutions in the Schrödinger and Klein–Gordon equations to unveiling the Dirac equation that shockingly foretold antimatter. Along the way, you’ll meet Dirac himself (the “strangest man in physics”), unpack Heisenberg’s uncertainty principle, and see how the positron emerged from math that seemed to point to an entire anti-universe.
Featuring insights from experts Graham Farmelo and Cumrun Vafa, plus rare archives from FSU and Caltech, this playful deep dive shows how one brilliant equation upended our view of reality—and hinted that antiparticles might just be us traveling backwards in time.
