Something Weird Happens When E = –mc²

Veritasium dives into Paul Dirac’s mind-bending journey from the failure of Schrödinger’s equation to his groundbreaking Dirac equation, where E = –mc² pops out “negative energy” solutions that physicists couldn’t ignore. Along the way, you’ll meet “the strangest man in physics,” wrestle with Heisenberg’s uncertainty principle, and witness how theory forced Dirac to rethink everything.

The real kicker? Dirac’s math didn’t just stay on paper—it predicted the positron (anti-electron) and suggested that antiparticles are just particles traveling backward in time. In doing so, he unlocked the door to a whole anti-world, forever changing our view of the universe.
