A feature of all things that spin is that, if they contract, they must also rotate faster. This is the universal principle called the Conservation of Angular Momentum (CAM).
This law has been creating and destroying our world for billions of years. On the earth, as the thunderheads of a storm build up they suck up hot air and contract. As they contract they spin faster and faster. In the most extreme cases, tornadoes form.
Even though this seems like a horribly destructive event, it is this same phenomenon that is responsible for creating the stability of our solar system. With all the gasses being pulled in on themselves everything would have eventually collapsed, but all that gravitational activity caused our Sun to ignite. This caused similar CAM events to happen and form the planets.
Once again, the Universe does not cease to amaze me. From destruction to beauty for billions of years, the same law has been at work.
