If you want to remember why you once fell in love with the idea of the cosmos, or want to fall in love with it for the first time, then this book is for you Observer From Carlo Rovelli, the bestselling author of Seven Brief Lessons on Physics, this is a story of wonder, new worlds and why the end is just the beginning Let us journey into the heart of a black hole. Let us slip beyond its boundary, the horizon, and tumble – on and on – down this crack in the universe. As we plunge, we’ll see geometry fold, we’ll feel the equations draw tight around us. Eventually, we’ll pass it: the remains of a star, deep and dense and falling further far. And then – the bottom. Where time and space end, and the white hole is born . . .With lightness and magic, here Carlo Rovelli traces the ongoing adventure of his own cutting-edge research, of the uncertainty and joy of going where we’ve not yet been. Guiding us to the edge of theory and experiment, he invites us to go beyond, to experience the fever and the disquiet of science. Here is the extraordinary life of a white hole.A BOOK OF THE YEAR ACCORDING TO THE FINANCIAL TIMES * SUNDAY TELEGRAPH * NEW STATESMAN * NEW SCIENTIST
