Book excerpt: Le Big Bang prouve-t-il l'existence de Dieu ? Dans quoi l'Univers se développe-t-il ? La Terre est-elle la seule planète abritant la vie ? Pourquoi le plus grand astronome de l'histoire a-t-il tué son élan de compagnie ? Saviez-vous qu'il neige du métal sur Vénus, qu'il y a des lacs souterrains sur Mars et des rivières de pétrole sur Titan ? L'espace est l’objet le plus grand, le plus ancien, le plus chaud, le plus froid et le plus étrange qu'un humain puisse étudier. Dans Magique Cosmos, Tim James nous emmène faire un tour de l'univers connu (et inconnu), tout en déballant les dernières théories sur ce qui s’y passe réellement. Il nous fait découvrir la science de l'espace dans ce qu'elle a de plus étrange. En nous guidant à travers la relativité d'Einstein, la mécanique quantique et la théorie des cordes, Magique Cosmos explore les recoins les plus déroutants de l’univers et s'attaque aux plus grands mystères auxquels nous sommes confrontés : de la vie extraterrestre au zodiaque ; des trous blancs aux trous de ver ; des quasars aux quarks. Tim James nous emmène aussi au-delà de notre système solaire, vers des exoplanètes qui pourraient abriter la vie et des planètes voyous. Il nous raconte la recherche d'intelligence extraterrestre, notamment la découverte de fossiles martiens dans la météorite Alan Hills, et le tentant "signal Wow" reçu par la Terre en 1973 - encore inexpliqué.

Download or read book Au coeur des trous noirs written by Aurélien Barrau and published by Dunod. This book was released on 2024-01-10 with total page 129 pages. Available in PDF, EPUB and Kindle. Book excerpt: Que sait-on des trous noirs ? Peut-on les observer ? Qu'y a-t-il à l'intérieur ? Existent-ils vraiment ? Les trous noirs sont des sphères dans l'espace dont rien ne peut s'échapper. De tels objets ne peuvent ni émettre, ni réfléchir la lumière, mais certains sont pourtant extraordinairement lumineux. Toutefois, ce n'est pas là leur seule bizarrerie : dans un trou noir, l'espace se change en temps, le temps en espace, et nul ne connaît la véritable nature de la singularité centrale. Sans sacrifier à la rigueur, cet ouvrage rend accessibles les grandes énigmes des trous noirs, en suivant le cheminement de pensée de deux personnages fictifs imaginés par Aurélien Barrau.

Book excerpt: Un astronaute sort de sa navette spatiale pour faire une réparation. Soudain, il entend une voix qui lui pose d’étranges questions et lui demande aussitôt ce qu’il pense des requins. Une voix ? Dans l’espace ? C’est un enfant au rire clair comme le cristal qui lui apparaît. Il s’appelle le Petit Principe. D’où vient-il ? Et comment peut-il même se trouver là ? Le Petit Principe évite de répondre à toutes ces interrogations. Il se contente d’être là. Voyageant d’un trou noir à l’autre, il va rencontrer les personnages les plus étonnants, et faire l’expérience de l’Univers qui est, aussi, l’expérience de la vie.

Download or read book The Little Book of Black Holes written by Steven S. Gubser and published by Princeton University Press. This book was released on 2017-10-10 with total page 197 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dive into a mind-bending exploration of the physics of black holes Black holes, predicted by Albert Einstein’s general theory of relativity more than a century ago, have long intrigued scientists and the public with their bizarre and fantastical properties. Although Einstein understood that black holes were mathematical solutions to his equations, he never accepted their physical reality—a viewpoint many shared. This all changed in the 1960s and 1970s, when a deeper conceptual understanding of black holes developed just as new observations revealed the existence of quasars and X-ray binary star systems, whose mysterious properties could be explained by the presence of black holes. Black holes have since been the subject of intense research—and the physics governing how they behave and affect their surroundings is stranger and more mind-bending than any fiction. After introducing the basics of the special and general theories of relativity, this book describes black holes both as astrophysical objects and theoretical “laboratories” in which physicists can test their understanding of gravitational, quantum, and thermal physics. From Schwarzschild black holes to rotating and colliding black holes, and from gravitational radiation to Hawking radiation and information loss, Steven Gubser and Frans Pretorius use creative thought experiments and analogies to explain their subject accessibly. They also describe the decades-long quest to observe the universe in gravitational waves, which recently resulted in the LIGO observatories’ detection of the distinctive gravitational wave “chirp” of two colliding black holes—the first direct observation of black holes’ existence. The Little Book of Black Holes takes readers deep into the mysterious heart of the subject, offering rare clarity of insight into the physics that makes black holes simple yet destructive manifestations of geometric destiny.

Book excerpt: Le bestiaire de l'astrophysique regorge de créatures étranges, supernovae apocalyptiques, étoiles à neutrons hyperdenses, ou discrètes naines blanches. Mais les plus mystérieuses et les plus excitantes sont sans conteste les trous noirs, d'une compacité extrême, invisibles, et pourtant - affirment les astrophysiciens - accidents ordinaires de notre espace-temps. L'auteur, spécialiste français de la question, fait ici la part des connaissances actuelles, des espoirs en matière d'observation et des spéculations théoriques. Un étonnant voyage aux confins de l'espace et du temps.
