Joseph Silk is the author of an authoritative book on the Big Bang. In the present work, he covers the history of the universe from that first great explosion and shows how the most recent discoveries in astrophysics i.e. of the cosmic fluctuations from which the great structures of the universe emerged provide the missing link between the Big Bang, which occurred 15 billion years ago, and the present state of the universe. When did time begin? This is the question, already asked by Stephen Hawking, that A Short History of the Universe sets out to answer. It is the subject of current debate among theologians: Did time begin with the Big Bang, in which case God could not have created the universe, or has time existed for all eternity, which would mean that the Big Bang was just one event among others, that God could have existed before it occurred and that He could thus have created the universe? This highly accessible book will be of interest to a wide readership, since the issues examined here concern all of us. Joseph Silk, an astrophysicist and cosmologist, teaches at Oxford University.
Man has begun to realize one of his most ancient dreams: to overcome gravity, to conquer space, to explore the universe. André Lebeau sheds light on some of the stakes of this quest. By examining the logic of evolution which drives us to explore, and then to occupy, discovered continents, Lebeau traces the perspectives that the possible colonization of outer space opens to humanity. In so doing, he offers a new viewpoint on the dynamics of scientific and technological progress.
