There is Only One Electron in the Universe | BRIAN GREENE

What if every electron in existence is not a separate particle, but the same single electron appearing at countless locations across space and time. This video explores one of the most radical and mathematically grounded ideas in theoretical physics, the one-electron universe hypothesis, which proposes that a single electron weaves its worldline through the entire history of spacetime, moving forward and backward through time to create the illusion of a vast multitude of identical particles. We break down the physics of quantum indistinguishability, the Dirac equation, antimatter as time-reversed matter, pair production, annihilation events, and CPT symmetry, all explained through vivid analogies and rigorous scientific reasoning. Discover why the perfect identity of every electron in the universe is not a manufacturing coincidence but a potential geometric truth about the structure of time itself. If you have ever wondered why matter and antimatter annihilate, why positrons behave like electrons running backward through time, or what quantum field theory really says about the nature of particles, this video delivers the answers with clarity, depth, and a sense of wonder that reshapes how you see physical reality. #electron #quantumphysics #theoreticalphysics #antimatter #positron #quantummechanics #diracequation #particlephysics #spacetime #quantumfieldtheory #oneuniverse #physicsexplained #timetravel #mattervantimatter #cosmology #bigbang #subatomicparticles #feynmandiagrams #physicslovers #sciencefacts #deepspace #universemystery #physicseducation #quantumworld #relativity #cptviolation #worldline #electronpositron #sciencevideos #mindblowingphysics #fundamentalphysics #physicstheory #modernphysics #highenergyphy #sciencecommunity #spacetimegeometry #physicsfun #physicsnerds #quantumreality #universefacts
