With an opinionated and irreverent tone, the author debunks most of the current theories in the field of modern physics, appealing to the scientific method and common sense. At the same time, in strict compliance with the already known experimental evidence, he proposes his own version of the facts, aimed at rationalizing and unifying the various aspects in which the nature that surrounds us manifests itself. The result is a possible model of the universe where events are all connected by a common thread, even if distributed on different scales, ranging from the subatomic to that of galaxies. In this perspective, in the middle, the living cell profits from a substrate and a habitat that have favoured its very existence. Reading of this book does not require any advanced scientific knowledge and is therefore accessible to non-experts, provided they are equipped with the necessary dose of eccentricity that allows them to appreciate these provocative pages.
