This book proposes a surprising new cosmological theory and a fresh look at physics, with the creation of a new one, called "rational" and competing with the classical and official physics. New hypothesis on the ether, experimentally upheld in laboratory, completely changes the vision of the Universe and gives smart answers to many questions not yet solved: why the suns are in rotation, why planets are on the same plane, why they are so different, and many others. If the Theory of Relativity, the Big Bang and Quantum Physics seem odd to you, this book will explain to you why. If you don't like physics, you'll change your mind.
