You can help support this channel via the Physics Explained Patreon account: https://www.patreon.com/physicsexplained Can electrons really spin — or is that idea fundamentally flawed? In this video, we break down a shocking paradox: if the electron were truly spinning like a sphere, its surface would exceed the speed of light. Classical physics falls apart, and we’re forced to confront the quantum reality of spin — one of the strangest and most precisely tested ideas in science.
