The One-Electron Universe | Space Time
Summary
This episode explores John Archibald Wheeler's "one-electron universe" hypothesis, which posits that all electrons are a single particle zigzagging through time, with its backward motion manifesting as positrons. The discussion details how this concept inspired Richard Feynman's path integral formulation, establishing the mathematical equivalence of antimatter and time-reversed matter. The host also addresses listener questions regarding the measurement of dark flow and the nomenclature of cosmic phenomena.
