Summary
Veritasium unpacks how Paul Dirac’s quest to reconcile quantum mechanics with special relativity led him to a wild prediction: negative-energy states that begged the question, “Does an anti-universe exist?” After showing why the Schrödinger equation falls short at relativistic speeds, we meet Dirac’s eponymous equation and learn how it forced physicists to accept the positron—an anti-electron that behaves like matter running backward in time.
Along the way, the video profiles Dirac himself (famously private and a bit odd), the drama of initial rejections by the physics community, and the profound implication that our universe might have a mirror realm of antimatter. It’s a whirlwind tour from faulty equations to one of the coolest concepts in modern physics.
