The physicist who changes our view of the universe. A true delight. An extremely captivating book. Rovelli is a charming, thought-provoking guide. Do space and time really exist? What is reality made of? Can we understand its deeper structure? Scientist Carlo Rovelli has spent his entire life exploring these questions and expanding the boundaries of our knowledge. In this mind-expanding book, he shows how our understanding of reality has changed over the centuries, from Democritus to loop quantum gravity. He takes us on a wonderful journey and invites us to imagine a whole new world where black holes are waiting to explode, space-time is made of grains, and infinity does not exist – a vast universe that is still largely unexplored.
