Einstein's Last Dream ebook

The dream Einstein left unfinished has a precise name: a theory that holds together general relativity and quantum mechanics, gravity and the world of the infinitely small. The work is still under way, and this book crosses its roughest ground: black holes and their entropy, the information paradox, firewalls, and the theoretical attempts to put the picture back together, from strings to loop quantum gravity to holography. The story starts from the media case of Sabrina Pasterski, hailed as "the next Einstein", to show the distance between the noise of an announcement and scientific proof – and it chooses to stay on the side of proof. For anyone who follows today's debate on fundamental physics, this book offers an honest map of what we know and what we do not yet know, without shortcuts and without celebrations. An invitation to look inside the workshop, where science is really made.
