The book outlines key conceptual steps connecting particles, inflation, strings, and ekpyrosis to a coherent framework for an endlessly evolving cosmos. It also contrasts competing perspectives on how the universe evolves, including the possibility of an inflationary multiverse versus a cyclic universe, culminating in questions about ultimate physical reality and evidence.","Endless Universe  \nPaul J.

The book could never have been completed without the love, patience, and support of Nancy and Corinne. Working on each side of the Atlantic, they were our most dedicated readers, our most exacting editors, our harshest critics, and our best morale boosters. Paul’s sisters, Alice and Nancy Steinhardt, and brother-in-law Bob Sorensen, and Neil’s parents, Ben and Mary, read early versions and gave vital guidance. Paul’s sister-in-law Chana Shapiro meticulously reviewed the manuscript and helped us to resolve numerous structural issues, especially how to design a story told with two voices. Our children, Charlie, Joe, Will, and Cindy Steinhardt, and Ruby TurokSquire, all helped to shape the text and the illustrations.  \nWe also are extremely grateful to the numerous colleagues who took time to read all or parts of the manuscript and to give us their valuable advice, including Andreas Albrecht, Brian Greene, Stephen Hawking, Burt Ovrut, Roger Penrose, Martin Rees, Michael Turner, and Edward Witten. Daniel Baumann, Jean-Luc Lehners, and Paul McFadden carefully reviewed the physics presentation throughout the manuscript. Michael Olenick contributed many useful comments. Peter Galison, Gerald  \nHolton, Peter Schaefer, and Jeffrey Tigay provided guidance on the historical issues discussed in Chapter 8. We thank Carl Feinberg for suggesting that we consider the relationship between the cyclic model and Asimov’s short story The Last Question.  \nMany have contributed to our scientific and personal lives, as well as to the ideas described herein. The imprint of our mentors, Richard Feynman, Sidney Coleman, David Olive, and Tom Kibble, can be found throughout this book. For Paul, Alan Guth was profoundly important in drawing him into the field of cosmology (see Chapter 5) . He, Michael Turner, and Andreas Albrecht were influencial early in Paul’s career and have been longstanding friends ever since. Many at Cambridge and Princeton have provided invaluable guidance, including John and Neta Bahcall, Gary Gibbons, David Gross, Stephen Hawking, Jerry Ostriker, Lyman Page, Jim Peebles, Malcolm Perry, Martin Rees, Nathan Seiberg, David Spergel, Scott Tremaine, David Wilkinson, and Edward Witten.  \nIn developing the cyclic model, we have been fortunate to have a cadre of outstanding collaborators. Burt Ovrut, a longtime collaborator and friend of Paul’s, started us down the path toward the cyclic model with his fateful talk in Cambridge in August 1999 (see Chapters 1 and 6) and
