Brian Greene

It is possible that there are many other universes that exist parallel to our universe. Theoretical physicist Brian Greene, author of The Elegant Universe, explains how that's possible in the new book, The Hidden Reality.

With his book, The Elegant Universe, physicist Brian Greene developed a reputation for explaining complex scientific theories with insight and clarity. The book was the basis for a PBS series. His new book is The Fabric of the Cosmos: Space, Time, and the Texture of Reality. Greene is a professor of physics and mathematics at Columbia University. He received his undergraduate degree from Harvard and his doctorate from Oxford, where he was a Rhodes scholar.
