RaveThe Observer (UK)\"Rovelli is an accomplished theoretical physicist, prolific author and lyrical science communicator. White Holes is a small book – Rovelli’s briefest yet – and smashes through a lot of material at breakneck speed, pretty much the entire content of A Brief History of Time in a couple of short chapters by way of overview and introduction. Reading it is more akin to the final psychedelic sequence in the movie 2001: A Space Odyssey: you’re not sure where you’re heading but it feels bloody exciting. In fewer pages than it would take some authors to describe how they would prepare an omelette, Rovelli drags you into the heart of a black hole and then – somehow – out the other side. What he suggests is that, as the star forming a black hole continues to collapse, it eventually becomes so compact and tiny that the laws of general relativity have to give way to the laws of quantum mechanics ... this is a book for the layperson and Rovelli understands this limitation, glossing over finer detail in pursuit of an impression of the wonder that lies at the heart of the cosmos and his theorising. And in his hands it’s an effective technique ... One of the things I most loved about White Holes was the glimpse Rovelli gives you into the mind of a physicist working at the edges of the known universe, and the fundamental insecurity of creating groundbreaking theories and then putting them out there like clay pigeons launched from a trap ... if you’re a final year undergraduate looking for revision notes to accompany your module in high energy astrophysics, this volume may disappoint. But if you want to remember why you once fell in love with the idea of the cosmos, or want to fall in love with that idea for the first time, then this book is for you. For my part, I found myself following Rovelli into a weird and wonderful new universe and I was very content to be there.\
