But was he right? Can the quantum theory of fields and Einstein's general theory of relativity, the two most accurate and successful theories in all of physics, be united into a single quantum theory of gravity? Can quantum and cosmos ever be combined? In \u003ci\u003eThe Nature of Space and Time\u003c\/i\u003e, two of the world's most famous physicists--Stephen Hawking (\u003ci\u003eA Brief History of Time\u003c\/i\u003e) and Roger Penrose (\u003ci\u003eThe Road to Reality\u003c\/i\u003e)--debate these questions. \u003cp\u003e\u003c\/p\u003eThe authors outline how their positions have further diverged on a number of key issues, including the spatial geometry of the universe, inflationary versus cyclic theories of the cosmos, and the black-hole information-loss paradox. Though much progress has been made, Hawking and Penrose stress that physicists still have further to go in their quest for a quantum theory of gravity.\u003cbr\u003e\u003cbr\u003e\u003cbr\u003e\u003cb\u003eAbout the Author\u003c\/b\u003e\u003cbr\u003e\u003cb\u003eStephen Hawking\u003c\/b\u003e (1942-2018) was the Lucasian Professor of Mathematics Emeritus at the University of Cambridge. \u003cb\u003eRoger Penrose\u003c\/b\u003e is a Nobel Prize-winning physicist and the author of \u003ci\u003eCycles of Time \u003c\/i\u003eand \u003ci\u003eThe Road to Reality \u003c\/i\u003e(both Vintage).
