?Qu''y avait-il avant le Big Bang ? Quelle est la source de l''ordre qui regne dans l''Univers ? Quel avenir cosmique nous attend ? Roger Penrose propose une nouvelle plongee dans les trefonds des mysteres de l''Univers et tente de repondre a ces trois questions fondamentales de la cosmologie. Selon lui, l''Univers en expansion et en acceleration pourrait creer les conditions pour qu''advienne un nouveau Big Bang. Passant en revue les modeles cosmologiques standard ou non, examinant ce qu''il en est des trous noirs ou du rayonnement cosmique et autres points cles de la physique contemporaine, il rejoint ainsi les speculations ancestrales sur le cours du temps et les origines du monde. Roger Penrose est professeur emerite de mathematiques a l''Universite d''Oxford. Il est notamment l''auteur d''A la decouverte des lois de l''Univers.

Einstein aimait à répéter que le plus incompréhensible dans l''univers est bien qu''il soit compréhensible. La chose est-elle si sûre ? La théorie quantique des champs et la théorie de la relativité générale d''Einstein sont à l''heure actuelle les deux théories les mieux vérifiées en physique : pourra-t-on les unifier en une théorie quantique de la gravité ? Celle-ci expliquerait toutes les singularités - les premières secondes de l''univers comme la physique de ces objets énigmatiques que sont les trous noirs. Notre intelligence de l''univers ferait alors un pas de géant. Mais quantique et cosmos peuvent-ils même être combinés ? Sur les questions cruciales de l''espace et du temps, qui manifestent les insuffisances des théories, deux des plus célèbres physiciens - Stephen Hawking et Roger Penrose - s''opposent dans un débat sans concession. En écho aux fameux débats qui opposèrent Bohr et Einstein sur les bizarres implications de la théorie quantique, cet ouvrage à deux voix donne à ses lecteurs l''occasion unique d''assister, aux premières loges, à l''élaboration, par la physique du XXIe siècle des grandes réponses aux énigmes sur lesquelles vient encore buter notre compréhension du cosmos.

Este volume fornece uma introdução acessível e iluminadora à posição de Penrose sobre as perspectivas da física teórica para o século XXI. Ele resume e atualiza as polêmicas idéias apresentadas em seus livros anteriores, A mente nova do rei e Shadows of the mind, e inclui contribuições marcantes de Abner Shimony, Nancy Cartwright e Stephen Hawking. É um livro profundo de uma das mais originais e instigantes mentes da ciência contemporânea.

Spinor and Twistor Methods in Space-Time Geometry introduces the theory of twistors, and studies in detail how the theory of twistors and 2-spinors can be applied to the study of space-time. Twistors have, in recent years, attracted increasing attention as a mathematical tool and as a means of gaining new insights into the structure of physical laws. This volume also includes a comprehensive treatment of the conformal approach to space-time infinity with results on general-relativistic mass and angular momentum, a detailed spinorial classification of the full space-time curvature tensor, and an account of the geometry of null geodesics.
