Zero, zip, nada, zilch. It''s all too easy to ignore the fascinating possibilities of emptiness and non-existence, and we may well wonder what there is to say about nothing. But scientists have known for centuries that nothing is the key to understanding absolutely everything, from why particles have mass to the expansion of the universe; without nothing we''d be precisely nowhere.

With chapters by 22 science writers, including top names such as Ian Stewart, Marcus Chown, Helen Pilcher, Nigel Henbest, Michael Brooks, Linda Geddes, Paul Davies, Jo Marchant and David Fisher, this fascinating and intriguing book revels in a subject that has tantalised the finest minds for centuries, and shows there''s more to nothing than meets the eye.
