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

Описание: 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

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.
