From the best-selling author of The Elegant Universe and The Fabric of the
Cosmos comes his most expansive and accessible book to date—a book that takes
on the grandest question: Is ours the only universe?
There was a time when “universe” meant all there is. Everything. Yet, in
recent years discoveries in physics and cosmology have led a number of
scientists to conclude that our universe may be one among many. With
crystal-clear prose and inspired use of analogy, Brian Greene shows how a range
of different “multiverse” proposals emerges from theories developed to explain
the most refined observations of both subatomic particles and the dark depths
of space: a multiverse in which you have an infinite number of doppelgängers,
each reading this sentence in a distant universe; a multiverse comprising a
vast ocean of bubble universes, of which ours is but one; a multiverse that
endlessly cycles through time, or one that might be hovering millimeters away
yet remains invisible; another in which every possibility allowed by quantum
physics is brought to life. Or, perhaps strangest of all, a multiverse made
purely of math.
Greene, one of our foremost physicists and science writers, takes us on a
captivating exploration of these parallel worlds and reveals how much of
reality’s true nature may be deeply hidden within them. And, with his unrivaled
ability to make the most challenging of material accessible and entertaining,
Greene tackles the core question: How can fundamental science progress if great
swaths of reality lie beyond our reach?
Sparked by Greene’s trademark wit and precision, The Hidden Reality is at once
a far-reaching survey of cutting-edge physics and a remarkable journey to the
very edge of reality—a journey grounded firmly in science and limited only by
