How We Proved Earth Rotates Using a Giant Swinging Ball
People have suspected that Earth rotates for thousands of years, but how did we first prove it? Hosted by: Stefan Chin ---------- Support SciShow by becoming a ...

[♪ INTRO] Right now, the Earth’s surface is spinning at several hundred meters per second, and we’re all along for the ride. It doesn’t actually feel like you’re moving, though. Which is nice, because being super dizzy all the time doesn’t sound like a fun way to live, but that also means that for a long time, we didn’t know for sure that the Earth was spinning at all. People have suspected the Earth rotates for thousands of years, but it wasn’t like they could just go to space and see for themselves, so it was hard to prove in a simple, clear way. Until 1851, when French physicist Leon Foucault hung a pendulum from one of the highest ceilings in Paris and let it swing. Before this, some astronomers as far back as the ancient Greeks thought the Earth rotated, because...
