An Electron Never Runs Out of Energy Why Not? | Feynman Reality Check

Why doesn’t an electron simply run out of energy? If it is always moving, always interacting, and always part of the invisible machinery of matter, where does that energy come from — and why doesn’t it disappear? In this 45-minute Feynman-style reality check, we explore one of the strangest questions in physics: why electrons do not behave like tiny planets slowly losing speed. From classical physics to quantum mechanics, from atomic stability to wave behavior, this video breaks down why the electron forced scientists to rethink motion, energy, matter, and reality itself. This is not just about electrons. It is about why atoms exist, why matter is stable, and why the universe does not collapse.
