One-Electron Universe
Summary
The article explains the one‑electron universe hypothesis: Wheeler’s idea that all electrons and positrons are different segments of a single particle’s world‑line moving forward and backward in time, with historical notes on Feynman and Stueckelberg.
- All electrons/positrons are described as one particle’s tangled world‑line in spacetime.
- Wheeler proposed the idea to Feynman in 1940; Feynman later used the backward‑time interpretation for antiparticles.
- The hypothesis is a historical footnote in quantum electrodynamics, not a practical engineering concept.
The piece is a historical physics anecdote; it offers no actionable insight for software engineers or system design.
