You’ve been told electricity flows through wires your entire life. Electrons in, energy out, like water through a pipe. But what if the wire is barely involved? What if the energy powering your lamp never actually travels inside the copper at all — and instead rushes through the empty space around it at the speed of light? In this video, we explore one of Feynman’s most provocative classroom demonstrations: the Poynting vector applied to a simple DC circuit. Drawing from Chapter 27 of The Feynman Lectures on Physics, Volume II, we walk through why electrons move absurdly slowly (slower than a snail), why energy arrives nearly instantaneously, and how John Henry Poynting’s 1884 discovery reveals that electromagnetic fields — not electrons — are the true carriers of electrical energy.
