The Strange Reason Why Everything Spins in the Universe
Close your eyes and let the quiet physics of the universe carry you into sleep. Everything spins because of a fundamental law called the conservation of angular momentum. When gas clouds collapsed to form our solar system, they began to spin faster, like an ice skater pulling their arms in. Planets, moons, and asteroids inherited that motion, which is why most orbit and spin in the same direction. Venus spins backwards, and Uranus spins on its side—both likely caused by ancient collisions. Let this gentle cosmic dance carry you into a deep and restful sleep.
