On the Origin of Time

Why is our universe the way it is? How did everything begin? How might it end? Thomas Hertog probed these overwhelming questions in collaboration with Stephen Hawking, achieving a privileged perspective into how, struggling against daunting physical odds, Hawking's imprisoned mind yielded astonishing insights even in his later years. This superbly written book offers insight into an extraordinary individual, the creative process generally, and the scope and limits of our current understanding of the cosmos. -Lord Martin Rees, Emeritus Professor of Cosmology and Astrophysics, University of Cambridge, and author of Just Six Numbers Like his mentor and colleague Stephen Hawking, Thomas Hertog has never shied away from being ambitious in theorizing about the universe. This sweeping book provides an accessible overview of both what we know about cosmology and some audacious ideas for moving into the unknown. It is an introduction to Hawking's final theory, but also a glimpse into even grander theories yet to come. -Sean Carroll, author of The Biggest Ideas in the Universe: Space, Time, and Motion Stephen Hawking's final theory is lucidly explained in this splendidly accessible book. Author Thomas Hertog, one of Hawking's closest collaborators, gives us a vivid insight into Hawking as both a brilliant physicist and an astonishingly determined human being. -Graham Farmelo, Churchill College, University of Cambridge, and author of The Strangest Man A beautifully written, thought-provoking account of both the physics and the personalities involved in Hawking's visionary struggle to comprehend the cosmos. Thomas Hertog has provided a fascinating insider's view. -Neil Turok, co-author of Endless Universe
