The Pulitzer Prize–nominated physicist who wrote The Elegant Universe here illuminates some of the most mysterious of concepts about space and time. Is space an entity? Why does time have a direction? Could the universe exist without space and time? Can we travel to the past? Brian Greene uses these questions to guide us toward modern science's new and deeper understanding of the universe. He reveals our world to be very different from what common experience leads us to believe, and shows how cutting-edge developments in superstring and M-theory may reconcile the behavior of particles and black holes.
"Using images as simple as that of Homer Simpson riding a skateboard and an ordinary earthworm crawling along a tightrope, Greene draws readers deep into revolutionary new conceptions of space and time.... [He] deepens his inquiries with occasional ventures into scholarly complexities."—Booklist (starred review)
