Feynman Explains Why Light Does Not Move

What if light isn’t “moving” the way you think it is? We say light travels at 299,792,458 meters per second. We imagine it racing across space from the Sun to your eyes. But according to modern physics — and the spacetime geometry taught by Richard Feynman — the story is far stranger. From light’s own perspective… nothing happens. No time passes. No distance exists. So in what sense does light actually move? In This Video, We Explore: ⚡ The Speed of Light as the Speed of Causality Why c is not just a speed — it’s the fundamental limit built into spacetime itself. 🕰 How Time Stops for a Photon Using relativity, we show why a light-like path has zero elapsed time. 📐 The Geometry of Spacetime How Minkowski space reveals that light’s path has zero spacetime interval — meaning no “experience” of travel. 🌌 Light Cones & Zero-Length Paths Why photons exist only on the boundary between space and time. 🔀 Quantum Electrodynamics (QED) From Feynman’s book QED, we explore the shocking rule: a photon doesn’t take one path — it takes all possible paths. 🤝 Wheeler–Feynman Absorber Theory The radical idea that emission and absorption are part of a single spacetime “handshake.” ✨ Your Connection to the Stars If light experiences no time, then the photon leaving a distant star and entering your eye is part of one indivisible event. This narrative draws from: The Feynman Lectures on Physics (Relativity & Spacetime) Six Not-So-Easy Pieces QED: The Strange Theory of Light and Matter The Character of Physical Law Feynman’s absorber theory work with John Wheeler Relativity tells us light experiences zero time. Quantum theory tells us it explores all paths. Spacetime geometry tells us its journey has zero length. So maybe light doesn’t “move” through time at all. Maybe it simply connects events. ⚠️ Disclaimer: This video features AI-generated narration inspired by Richard Feynman’s teaching style. It is not an authentic recording. The scientific explanations are based on established relativity and quantum electrodynamics. This project is for educational purposes. Light doesn’t travel the way you think. It doesn’t experience time. And in a very real sense… It never left the star.
