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.

Brian Greene received his undergraduate degree from Harvard University and his doctorate from Oxford University, where he was a Rhodes scholar. He is a professor of physics and mathematics at Columbia University and lives in New York City.
