The old paradigm of linear quantum mechanics is worn out. It is therefore urgent to replace it with a new approach, one which accepts a reality independent from the observer and which solves the paradoxes and enigmas that popular theories continue to stimulate. This book, in a language accessible not only to scholars but to everyone, exposes the insufficiencies of the orthodox and dominant linear quantum physics, and also demonstrates that time has come to bet on a new quantum physics, a causal and nonlinear physics, which for the time being is heterodox. We are invited here to view the most outstanding events in the history of astronomy and physics; we are also confronted with the epistemological debates that prove decisive to the future course of this area of knowledge; moreover, we are led to re-evaluate many conceptions which are, after all, fallacious, and supposedly integrate “true science”; and finally we are led, in rigor and clarity, through the meanders of an innovative interpretation of quantum physics, based upon the complexity and nonlinearity, which will be the foundation to the most promising research programmes.
