Paul Dirac’s quest to tame “negative energy” in quantum physics is wild: Schrödinger’s equation falls short, Heisenberg brings in uncertainty, and then the Dirac equation predicts a whole mirror universe of antimatter—complete with positrons zipping backward in time.
Derek Muller stitches together expert insights from Graham Farmelo and Cumrun Vafa, rare FSU and Caltech archives, and a handy timestamped breakdown (from “Can Negative Energy Exist?” to “The Anti-World”) to show how theory became reality and reshaped our view of the cosmos.
