You don’t have to be a genius or a rocket scientist to realize that the Universe is complex. You look out of the window: you see trees and plants, birds, human beings, cars, buildings. You look up in the sky, you see clouds and weather and then beyond that planets, and star, and galaxy. The Universe is full of tremendous diversity and complexity. Now why is this? Well, actually the answer is quite mysterious because really nobody knows. And in fact there is something really quite bizarre about the complexity of the Universe, because the one thing we do know about the Universe is the origins of the Universe itself.
