The universe was supposed to be all there was - the whole of existence. For centuries the size of the universe and whether or not it is finite, fascinated scientists and philosophers.But however big the universe may be, there being only one gave astronomers and cosmologists a headache. Existence as we know it is contingent on so many constants in nature which, if altered only slightly, would make life impossible. This seems so unlikely to happen by chance. What if, instead, there is in fact a vast range of different universes, with many variants of the universal contents, making ours just one of many that happens to be viable for life?In this illuminating exploration, Brian Clegg delves into the endless possibilities of the multiverse. Investigating questions of expanding, parallel and communicating universes, this accessible guide takes the reader into one of the weirdest and most exciting areas of modern physics and cosmology.

A NEW, FULLY ILLUSTRATED EDITION OF ANDREW MAYS ILLUMINATING GUIDE TO LIFE NOT ON EARTHThe possibility that alien life exists in the universe is among the most profound of human conjectures, which today is being investigated not just by science-fiction writers but by scientists.Astrobiology presents an expert guide to this compelling field of science. It shows how the tell- tale signatures of life on Earth might hold the key to detecting life beyond our planet; explores the many planets beyond our Solar System discovered by NASAs Kepler and TESS missions; and explains alien- hunting touchstones such as Fermis Paradox, the Drake Equation, and the Wow signal.As NASAs rovers burrow into Mars and its probes peer ever further into the cosmos, this illustrated edition combines deep space images with infographics to cast a scientific eye over the most significant of scientific treasure hunts.
