Richard Feynman Explains Why Light Doesn’t “Move” the Way You Think

What if light doesn’t actually move? This lecture explores that radical idea through the physics and insights of Richard Feynman, drawing from Einstein’s relativity and quantum electrodynamics (QED). We examine light not as something traveling through space in the usual sense, but as a phenomenon that reshapes how we understand time, causality, and connection. In this lecture, we explore: Why the speed of light is really the speed of causality How time stops for a photon The quantum rule that a photon takes all possible paths The spacetime geometry showing that light follows zero-length paths Why you are, in a deep physical sense, directly connected to the stars Foundations in Feynman’s Work This presentation is grounded in Feynman’s own writings and lectures, including The Feynman Lectures on Physics, QED, and Six Not-So-Easy Pieces. Part 1: Relativity and the Speed of Light The Feynman Lectures on Physics, Vol. I, Ch. 15 — the constant speed of light and the Michelson–Morley experiment Six Not-So-Easy Pieces, Ch. 3 — relativity of simultaneity and the limits of common sense QED, p. 49 — why light’s speed is independent of the observer Part 2: Time and the Photon The Feynman Lectures, Vol. I, §15-4 — time dilation and length contraction Six Not-So-Easy Pieces, Ch. 4 — approaching the speed of light The standard result of relativity: light experiences zero proper time Part 3: Spacetime Geometry The Character of Physical Law, Ch. 2 — the geometric nature of physics Six Not-So-Easy Pieces, Ch. 5 — Minkowski spacetime, intervals, and light cones Why c defines the ultimate limit of cause and effect Part 4: Quantum Electrodynamics QED: The Strange Theory of Light and Matter — photons as particles, probability amplitudes, and the rule that light explores all paths Part 5: Absorber Theory and Quantum Connections Feynman–Wheeler absorber theory Reflections from Surely You’re Joking, Mr. Feynman! Ideas related to entanglement, non-locality, and quantum “handshakes” Part 6: Synthesis and Wonder The Character of Physical Law, Ch. 7 — beauty and simplicity in nature The Meaning of It All — science, doubt, and awe Disclaimer The voice of Richard Feynman in this video is an AI-generated simulation, created for educational purposes. The script is based on Feynman’s published works, combined with modern scientific explanations. This lecture challenges everyday intuition and invites you into a deeper view of reality—where light doesn’t merely travel through spacetime, but defines it.
