I can't praise this book enough! This gifted author, a renowned astronomer, discusses the various ways in which our world could end due to catastrophes of a cosmological/astrophysical nature. In order to do this, he must explain the scientific principles involved and relate them to the ways in which we could meet our end - in morbid detail. For all of these events, probabilities are given regarding their possibly occurring during our own lifetimes, as well as whether any are actually preventable. The prose is simply outstanding; it leaves the reader breathless! The author's passion and excitement for his subject matter are quite contagious. Not only is the writing style clear and authoritative, but it's also immensely accessible. Using wit, humor, excellent analogies and everyday language, the author weaves each potential disaster tale in such a way that both general readers and scientists alike can relish them. Reading this book is the most pleasant way that I can think of for learning of human-race-annihilating disasters. This book can be enjoyed by anyone!
