Reality is Not What It Seems
The Elusive Structure of the Universe
di Carlo Rovelli
publisher: Raffaello Cortina Editore
"If we try to combine everything we have learned on the physical world in the XX century, evidence points towards something very different from what we learned at school about space, time, matter and energy. What emerges in an elementary structure of the world where time does not exist, space does not exist, generated by a swarming of quantum microevents. Quantum fields draw-up space, time, matter and light, trading information between one event and the other. Reality is weaved by a net of granular events; the dynamics tying them up is probabilistic; between one event and the other, space, time, matter and energy melt into a cloud of probability".“Time, space and matter are generated by a swarm of elementary quantum events. Understanding such deep texture of reality is the goal of quantum gravity, major 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. He describes how our image of the world has changed, from antiquity to the most recent discoveries: evaporation of black holes, universe before the big bang, granular structure of space, role of information, absence of time in fundamental physics. "He draws a vast fresco of the physical vision of the world, clarifies the content of theories such as general relativity and quantum mechanics, brings us to the forefront of present-day knowledge and offers an original and articulate account of the main issues now open. Above all, he passionately communicates the fascination of this research, the enthusasm driving it, and the beauty of the new perspective on the world which science reveals to us". "How is it possible that Carlo Rovelli has been able to write an essay in physics that kidnapes your attention from the first line to the last like the most absorbing of the novels? This is perhaps one of the few quantions not faced in the book. 'Reality is not What it Seems' is a marvelous book, with a stunningly vast vision of physics."
