Is ours the only universe?
From recent theories developed to explain the behavior of subatomic particles and the dark recesses of space come the “multiverse” theory that proposes not one but an infinite number of universes. One might contain an infinite number of doppelgangers, one might be a huge sea of bubble universes or be made purely of mathematics. With wit and precision, physicist and science writer Brian Greene explores these parallel worlds and reveals how our concept of reality is challenged by their possible existence. How can fundamental science proceed if huge swaths of reality are outside of our reach?
