But they are among the most fascinating and counter-intuitive objects in the universe. Not to mention that they are, in Marcus’s phrase, “the stuff of physicists’ nightmares.” Why?

Lawrence Krauss – The Known Unknowns: The Unsolved Mysteries of the Cosmos
Lawrence Krauss – Head Of Zeus – £20.00 Professor Lawrence Krauss has made major contributions to the field of theoretical physics and is one of the world’s great scientific communicators with a gift for illuminating complex ideas.
