The Hidden Reality: Parallel Universes and the Deep Laws of the Cosmos

The bestselling author of The Elegant Universe and The Fabric of the Cosmos tackles perhaps the most mind-bending question in modern physics and cosmology: Is our universe the only universe?

There was a time when "universe" meant all there is. Everything. Yet, a number of theories are converging on the possibility that our universe may be but one among many parallel universes populating a vast multiverse. Here, Briane Greene, one of our foremost physicists and science writers, takes us on a breathtaking journey to a multiverse comprising an endless series of big bangs, a multiverse with duplicates of every one of us, a multiverse populated by vast sheets of spacetime, a multiverse in which all we consider real are holographic illusions, and even a multiverse made purely of math--and reveals the reality hidden within each.

Using his trademark wit and precision, Greene presents a thrilling survey of cutting-edge physics and confronts the inevitable question: How can fundamental science progress if great swaths of reality lie beyond our reach? The Hidden Reality is a remarkable adventure through a world more vast and strange than anything we could have imagined.

Oliver Sacks on The Hidden Reality

Oliver Sacks was born in London and educated in London, Oxford, California, and New York. He is professor of neurology and psychiatry at Columbia University, and Columbia's first University Artist. He is the author of many books, including Awakenings, The Man Who Mistook His Wife for a Hat, and Musicophilia. His newest book, The Mind's Eye, was published in October, 2010.

Brian Greene is not only a profound cosmological thinker--a pioneer of string theory--but a writer of exceptional clarity and charm. His books--The Elegant Universe and The Fabric of the Cosmos among them--take one ever deeper into a universe stranger and more wonderful than anyone could have conceived a generation ago. The Hidden Reality takes us deeper still, and it has a special personal quality and warmth that is evident from the opening of the book, when Greene recollects how, as a boy, he was fascinated by the multiple reflections in parallel mirrors. He has never lost this childlike wonder at the world of physics, but he brings it now to examining theories of multiple universes, of the continual birth of universes, starting long before our own. . . and destined to continue, perhaps, to the end of time.

In the 1930s, as a boy myself, I read The Mysterious Universe by James Jeans. Jeans was, like Greene, a brilliant theoretical astronomer and equally mesmerizing writer. I thought Jeans's book was the most exciting, revelatory book I had ever read, and now, seventy years later, I feel the same excitement reading Brian Greene's new book, where every chapter opens level after level of previously unimaginable, mind-expanding realities.
