Why Does Everything in the Universe Spin?

Right now, without moving a single muscle, you are spinning at over 1,600 kilometres per hour. The Earth rotates on its axis. The Earth orbits the Sun. The Sun orbits the center of the Milky Way. And the Milky Way moves through the universe at over 2 million kilometres per hour. Everything in the universe spins. Planets, stars, galaxies, black holes. And that spin is not a side effect. It is one of the fundamental reasons everything alive is alive. If it stops, everything dies. In this video we go deep into the science behind cosmic rotation. We explain where all that spinning comes from, starting with the conservation of angular momentum and the collapse of the original gas cloud that formed our solar system. We cover why Venus rotates backwards and why a day on Venus is longer than a year. We explain what Vera Rubin discovered about galaxy rotation curves and how that led to the discovery of dark matter. We break down how Einstein predicted that spinning massive objects actually drag spacetime around them, a phenomenon confirmed by NASA's Gravity Probe B in 2011. And we walk through exactly what would happen to Earth if its rotation ever stopped, from the atmosphere to the magnetic field to the geological consequences. This is the force that sustains the universe. And most people have never thought about it once.
