` The physicist transforming how we see the universe` (Financial Times)` An utter joy` (Adam Rutherford)`A hugely engaging book... Rovelli is a charming, thought-provoking tour guide` (Manjit Kumar Prospect) Do space & time truly exist? What is reality made of? Can we understand its deep texturescientist Carlo Rovelli has spent his whole life exploring these questions & pushing the boundaries of what we know. In this mind-expanding book, he shows how our understanding of reality has changed throughout centuries, from Democritus to loop quantum gravity. Taking us on a wondrous journey, he invites us to imagine a whole new world where black holes are waiting to explode, spacetime is made up of grains, & infinity does not exist -- a vast universe still largely undiscovered.
