In this video, Derek dives into Paul Dirac’s groundbreaking work on negative energy solutions in quantum mechanics. After showing why the Schrödinger and Klein-Gordon equations stumbled with relativity, Dirac introduced his eponymous equation—uniting quantum theory and special relativity and predicting states of negative energy.
The kicker is that those weird negative-energy states paved the way for antimatter: the positron, particles traveling backward in time, and the notion of a hidden “anti-world.” Dirac’s theory not only foretold the anti-electron but also flipped our understanding of physics on its head.
