Answerable and Unanswerable QuestionsDoes alien life exist? Is time travel possible? How did the Universe begin and how will it end? Is the future pre-determined? These are just some of the fascinating questions posed in this book which stretches across physics, the life sciences and cosmology. Each chapter considers a separate question and ends with either an answer or, if there is insufficient evidence, a 'best guess' answer. For every question addressed here-be it time travel, multiple universes, intergalactic travel, or the end of the world-the author has tried to exhaust all possibilities before arriving at a conclusion. Everyone will have their own opinion but one thing is certain-Mysteries of the Universe will fascinate, educate, and stimulate."I really like the premise of this book... The questions are just those that a lay person wants the answers to and the division into answerable and unanswerable makes a distinction that is not always apparent." ANDREW NORTON, Professor of Astrophysics Education, The Open University, UK
