Reality is not what it appears to us
Author: Carlo Rovelli
Time, space and matter appear to be generated by a swarm of elementary quantum events. Understanding this profound texture of reality is the goal of research in quantum gravity, the challenge of contemporary science where all our knowledge about nature is called into question. Carlo Rovelli, one of the main protagonists of this adventure, leads the reader to the heart of the investigation in a simple and compelling way. It tells how our image of the world has changed from Antiquity to the most recent discoveries: the evaporation of black holes, the Universe before the big bang, the granular structure of space, the role of information and the absence of time in fundamental physics. The author draws a vast fresco of the physical worldview, clarifies the content of theories such as general relativity and quantum mechanics, takes us to the edge of current knowledge and offers an original and articulated version of the main questions open today. Above all, it communicates the charm of this research, the passion that animates it and the beauty of the new perspective on the world that science reveals to our eyes.
