• Pourquoi y a-t-il des atomes, des planètes et des humains plutôt que rien ? Comment pouvons-nous aimer, créer, croire, agir, penser... alors que notre cerveau est le fruit des lois déterministes de la physique ? La conscience est-elle apparue par la seule grâce du hasard ? Et si les étoiles sont appelées à terme à se consumer, les galaxies à se disperser et les trous noirs à s'évaporer comme l'a prédit Stephen Hawking, quel sens donner à notre existence ?
    Vulgarisateur hors pair, Brian Greene s'attaque à ces questions profondes en nous contant non seulement l'histoire longue de l'Univers, mais aussi son futur. Du Big Bang jusqu'à la fin des temps, il propose une quête aux confins de la science, interrogeant au passage l'éphémère beauté du monde.
    Une vertigineuse méditation cosmique par l'un des plus grands physiciens de notre temps.

  • Sans aucun doute le premier livre scientifique à explorer de façon aussi brillante et compréhensible l'idée d'univers parallèles, qui semblait n'appartenir qu'à la science-fiction.

    Oubliez vos certitudes ! Au-delà des étoiles, galaxies, amas de galaxies, que vous connaissez bien, il existe une " réalité cachée ".
    Loin d'être une idée de science-fiction, il s'agit d'un concept scientifique nouveau (né de neuf théories physico-mathématiques différentes) : les " univers parallèles ". Ajoutés au nôtre, ils composent cet étrange objet que les théoriciens nomment aujourd'hui " multivers ", au sujet duquel fusent alors de multiples interrogations : est-il fini ou infini ? est-il formé de milliards de milliards d'" universbulles " qui se côtoient sans interagir ? tiendrait-il de l'hologramme ? ou bien, comme le prédit la théorie des cordes, y aurait-il des univers cachés dans un monde de " branes ", étranges membranes à quelques millimètres seulement de nous, mais dissimulées à nos yeux ?
    Pour répondre à ces questions, Brian Greene nous entraîne dans une réflexion vertigineuse, au côté des plus grands : Albert Einstein et sa théorie de la relativité ou l'Écossais Peter Higgs, père du fameux " boson " découvert en juillet 2012 au CERN de Genève (le plus important laboratoire mondial de physique des particules). C'est à une nouvelle révolution cosmologique et mentale que La Réalité cachée nous invite. Car, de même que la Terre, jadis, perdit son statut de centre du monde, puis notre Soleil et notre Galaxie, c'est à notre propre univers d'abandonner à son tour son statut central, et de devenir un parmi d'autres.

  • In this exhilarating new book, Brian Greene explores our most current understanding of the universe, its deepest laws of nature, and our continuing quest to know more.The Hidden Reality reveals how major developments in different branches of fundamental theoretical physics-relativistic, quantum, cosmological, unified, computational - have all led us to consider one or another variety of parallel universe. In some, they are separated from us by enormous stretches of space or time, in others they're hovering millimetres away, in others still the very notion of their location proves to be a concept beyond our reach. Most extraordinarily, Greene shows how all of these parallel universe proposals emerge unbidden from the mathematics of theories developed to explain conventional data and observations of the cosmos. This is a life-changing book that gives us a true sense of the astounding possibilities of modern scientific investigation.

  • 'A magnificent challenge to conventional ideas' Financial Times'I thoroughly enjoyed this book. It manages to be both challenging and entertaining: it is highly recommended' the Independent '(Greene) send(s) the reader's imagination hurtling through the universe on an astonishing ride. As a popularizer of exquisitely abstract science, he is both a skilled and kindly explicator' the New York Times'Greene is as elegant as ever, cutting through the fog of complexity with insight and clarity; space and time become putty in his hands' Los Angeles Times Book Review

  • In a rare blend of scientific insight and writing as elegant as the theories it explains, Brian Greene, one of the world's leading string theorists, peels away the layers of mystery surrounding string theory to reveal a universe that consists of eleven dimensions, where all matter is generated by the vibrations of microscopically tiny loops of energy. Greene uses everything from an amusement park ride to ants on a garden hose to explain the beautiful yet bizarre realities that modern physics is unveiling. Dazzling in its brilliance, unprecedented in its ability to both illuminate and entertain, The Elegant Universe is a tour de force of scientific writing - a delightful, lucid voyage through modern physics that brings us closer to understanding how the universe works.

  • From Brian Greene, one of the world’s leading physicists and author the Pulitzer Prize finalist The Elegant Universe, comes a grand tour of the universe that makes us look at reality in a completely different way.
    Space and time form the very fabric of the cosmos. Yet they remain among the most mysterious of concepts. Is space an entity? Why does time have a direction? Could the universe exist without space and time? Can we travel to the past? Greene has set himself a daunting task: to explain non-intuitive, mathematical concepts like String Theory, the Heisenberg Uncertainty Principle, and Inflationary Cosmology with analogies drawn from common experience. From Newton’s unchanging realm in which space and time are absolute, to Einstein’s fluid conception of spacetime, to quantum mechanics’ entangled arena where vastly distant objects can instantaneously coordinate their behavior, Greene takes us all, regardless of our scientific backgrounds, on an irresistible and revelatory journey to the new layers of reality that modern physics has discovered lying just beneath the surface of our everyday world.

  • From the best-selling author of The Elegant Universe and The Fabric of the Cosmos comes his most expansive and accessible book to date--a book that takes on the grandest question: Is ours the only universe?
    There was a time when "universe" meant all there is. Everything. Yet, in recent years discoveries in physics and cosmology have led a number of scientists to conclude that our universe may be one among many. With crystal-clear prose and inspired use of analogy, Brian Greene shows how a range of different "multiverse" proposals emerges from theories developed to explain the most refined observations of both subatomic particles and the dark depths of space: a multiverse in which you have an infinite number of doppelgängers, each reading this sentence in a distant universe; a multiverse comprising a vast ocean of bubble universes, of which ours is but one; a multiverse that endlessly cycles through time, or one that might be hovering millimeters away yet remains invisible; another in which every possibility allowed by quantum physics is brought to life. Or, perhaps strangest of all, a multiverse made purely of math.
    Greene, one of our foremost physicists and science writers, takes us on a captivating exploration of these parallel worlds and reveals how much of reality';s true nature may be deeply hidden within them. And, with his unrivaled ability to make the most challenging of material accessible and entertaining, Greene tackles the core questin: How can fundamental science progress if great swaths of reality lie beyond our reach?
    Sparked by Greene';s trademark wit and precision, The Hidden Reality is at once a far-reaching survey of cutting-edge physics and a remarkable journey to the very edge of reality--a journey grounded firmly in science and limited only by our imagination.
