What If Charge is NOT Fundamental?
Summary
PBS Space Time explores the true nature of electric charge, tracing its origins from Heisenberg’s isospin to Gell-Mann’s quark model. The episode reveals that charge is not fundamental but emerges from the electroweak force, specifically through the mixing of weak isospin and hypercharge. It explains how the breaking of electroweak symmetry in the early universe separated these forces, linking charge to the Higgs field and the birth of the cosmos.
