La 4ème de couv : " De nombreuses observations confirment la théorie du "big bang", selon laquelle l'Univers a commencé dans un état extrêmement chaud et concentré. L'étude du fond cosmologique micro-onde, le plus ancien rayonnement électromagnétique que nous connaissions, a permis de mettre en évidence que l'univers a connu d'infimes fluctuations qui ont donné naissance aux galaxies. Aujourd'hui, nous savons avec certitude que l'Univers est en expansion. Les galaxies s'éloignent les unes des autres à une vitesse proportionnelle à leur distance : c'est la loi de Hubble-Lemaître. Mais l'expansion s'accélère. En cause : une mystérieuse énergie noire. Pour l'expliquer - et donc unifier relativité générale et physique quantique-, certaines hypothèses postulent que notre Univers ne serait qu'un parmi d'autres multivers. Un surprenant voyage dans l'espace, et donc... dans le temps !

A new look at the first few seconds after the Big Bang-and how continuing research into these moments may transform cosmology and physicsScientists in the past few decades have made crucial discoveries about how our cosmos evolved over the past 13.8 billion years. But there remains a critical gap in our knowledge: we still know very little about what happened in the first seconds after the Big Bang. At the Edge of Time focuses on what we have recently learned and are still striving to understand about this most essential and mysterious period of time at the beginning of cosmic history.Taking readers into the remarkable world of cosmology, Dan Hooper describes many of the extraordinary and perplexing questions that scientists are asking about the origin and nature of our world. Hooper examines how we are using the Large Hadron Collider and other experiments to re-create the conditions of the Big Bang and test promising theories for how and why our universe came to contain so much matter and so little antimatter. We may be poised to finally discover how dark matter was formed during our universe's first moments, and, with new telescopes, we are also lifting the veil on the era of cosmic inflation, which led to the creation of our world as we know it.Wrestling with the mysteries surrounding the initial moments that followed the Big Bang, At the Edge of Time presents an accessible investigation of our universe and its origin.

Notre Univers a-t-il un début ? Est-il unique ?La science moderne a révolutionné notre compréhension de l’Univers. Il est maintenant possible de connaître certains aspects des processus qui eurent lieu moins d’un milliardième de milliardième de milliardième de seconde après le Big Bang.Dans cette nouvelle édition actualisée, Aurélien Barrau décrit le cosmos qui se dessine sous nos yeux. Trous noirs, modèle standard de la physique des particules, gravité… les piliers et les énigmes du Big Bang sont abordés les uns après les autres, à la manière d’une balade aux origines de l’Univers.

De l'Antiquité à la Renaissance, la notion d'harmonie a lié mathématiques, astronomie et musique. Renouant avec cette tradition millénaire, Jean-Philippe Uzan fait dialoguer sons et lumières, science et musique en convoquant aussi bien Pythagore et Kepler que Bach et les Beatles. Dans son essai tout en poésie et en finesse, cet astrophysicien mélomane nous propose d'écouter le chant des étoiles, les vibrations du cosmos et le cri du big bang. Balade cosmique vertigineuse, L'harmonie secrète de l'Univers nous invite à questionner notre relation à l'Univers et le sentiment de mystère qu'il éveille en nous.

« Les règles et les lois sont les piliers de la société. J’aime les règlements. » C’est ainsi que le physicien Sheldon Cooper, l’un des personnages principaux de la série télévisée The Big Bang Theory, exprime sa passion pour l’univers du droit. Il consacre d’ailleurs aux subtilités juridiques une énergie au moins aussi enthousiaste que celle dont il fait preuve, dans sa mission de chercheur à l’université Caltech, pour comprendre les lois régissant le cosmos. Et l’existence n’est guère paisible pour ses amis – Leonard, Howard, Raj, Amy, Bernadette et, bien entendu, Penny – qui doivent subir son attirance infinie, sinon démesurée, pour la « norme », les « contrats » et tout ce qui touche à la « procédure ». Fort d’une pensée juridique originale, parfois excentrique, mais toujours cohérente, c’est donc à un véritable voyage dans les espaces du droit auquel nous invite Sheldon Cooper. Car The Big Bang Theory n’est pas seulement l’une des séries comiques les plus populaires des débuts du xxiesiècle. Elle constitue une réflexion ambitieuse sur les moyens et les fins du droit dans une société complexe à la recherche inlassable de son point d’équilibre.

Based on Prof. Lüst's Masters course at the University of Munich, this book begins with a short introduction to general relativity. It then presents black hole solutions, and discusses Penrose diagrams, black hole thermodynamics and entropy, the Unruh effect, Hawking radiation, the black hole information problem, black holes in supergravity and string theory, the black hole microstate counting in string theory, asymptotic symmetries in general relativity, and a particular quantum model for black holes. The book offers an up-to-date summary of all the pertinent questions in this highly active field of physics, and is ideal reading for graduate students and young researchers.

Regarding his discoveries, Sir Isaac Newton famously said, "If I have seen further it is by standing upon the shoulders of giants." The Evolving Universe and the Origin of Life describes, complete with fascinating biographical details of the thinkers involved, a history of the universe as interpreted by the expanding body of knowledge of humankind. From subatomic particles to the protein chains that form life, and expanding in scale to the entire universe, this book covers the science that explains how we came to be. This book contains a great breadth of knowledge, from astronomy and physics to chemistry and biology. The second edition brings this story up to date, chronicling scientific achievements in recent years in such fields of research as cosmology, the large-scale architecture of the universe, black holes, exoplanets, and the search for extraterrestrial life. With over 250 figures, this is a non-technical, easy-to-read textbook at an introductory college level that is ideal for anyone interested in science as well as its history.
