The Hidden Universe

Parallel Universes and the Deep Laws of the Cosmos

“There was a time when ‘universe’ meant ‘all there is,’” writes Greene, “but soon we may have to redefine that word, along with our own meager understanding of the cosmos.” A theoretical physicist and celebrated author, Greene offers intrepid readers another in-depth yet marvelously accessible look inside the perplexing world of modern theoretical physics and cosmology. Greene’s book The Elegant Universe explained late 20th-century efforts to find a unified theory of everything, culminating with string theory. But string theory opened up a new can of worms, hinting at the possible existence of multiple universes and other strange entities. The possibility of other universes existing alongside our own like holes in “a gigantic block of Swiss cheese” seems more likely every day. Beginning with relativity theory, the Big Bang, and our expanding universe, Greene introduces first the mind-blowing multiplicity of forms those parallel universes might take, from patchwork quilts or stretchy “branes” to landscapes and holograms riddled with black holes. With his inspired analogies starring everyone from South Park’s Eric Cartman to Ms. Pac-Man and a can of Pringles, Greene presents a lucid, intriguing, and triumphantly understandable state-of-the-art look at the universe.
