What is time? What is space?
Author: Carlo Rovelli
In this book, written with agile and fluent language, the author tells his own human, intellectual and scientific path, which starts from the youthful rebellion to continue in a scientific research felt as a fascinating adventure and as a model of thinking open to the new, which he rejects rules and dogmas and wants to look at the world "always with new eyes". Rovelli describes in a simple way the recent results of the theory of quantum gravity, the theory that combines general relativity and quantum mechanics, and tells us that space is made up of "grains of space" and that "time does not exist"; it also explains why black holes are hot and how to study the beginning of the Universe.
