Cycles of Time: An Extraordinary New View of the Universe
“The hyper-density of this book made my brain feel simultaneously wiped out and dazzled.”            -Boston GlobeBest Science Books of 2011 “Radical . . .  A surprising and unorthodox work disguised in the jacket of a popular science book,Cycles of Timeshould prove both deeply enlightening and just as deeply mystifying for anyone who dares to follow along.”            -Peter Woit,The Wall Street Journal “An intellectual thrill ride . . . As Penrose builds a solid foundation for his argument in analyzing universal entropic accumulation and Newton’s Second Law, the reader senses something tremendous looming—mysterious and compelling as a black hole . . . A cosmological page-turner.”            -Y. S. Fing,Washington Independent Review of Books “If you’ll forgive a skiing metaphor,Cycles of Timeis a black diamond of a book. But like all steep slopes, sometimes you take a moment from your struggles and look up, and in front of you is an utterly gorgeous view.”            -Anthony Doerr,Boston Globe “Profound . . . This fascinating book will surely become a classic in the history of cosmology.”            -Choice “Controversial but intriguing . . . Well worth the effort.”            -Kirkus “Intriguing . . . Penrose makes provocative arguments for his challenging new theory.”                             -Publishers Weekly
