This book is a compilation of the lectures for a one-semester course on gravitation at the University of Rochester. Starting from a simple description of geometry, the topics are systematically developed to the big bang theory with a simple derivation of the cosmic background temperature. Several informative examples are worked out in detail as well.

The three greatest scientific mysteries, which remain poorly understood, are the origin of the universe, the origin of life and the development of consciousness. This book describes the processes preceding the Big Bang, the creation of matter, the concentration of that matter into stars and planets, the development of simple life forms and the theory of evolution that has given higher life forms, including mankind.There are many popular and excellent science books that present various aspects of science. However, this book follows a narrow scientific pathway from the Big Bang to mankind, and d

En 1931, dans un court article dans la revue Nature, Georges Lemaître proposa que toute la matière présente dans l’univers physique provienne de la pulvérisation de l’atome primitif. Le concept de l’atome primitif fut l’embryon de la théorie du big bang, reprise par d’autres cosmologistes et savamment développée durant la seconde moitié du xxe siècle. L’hypothèse de l’atome primitif : essai de cosmogonie, une série de conférences données entre 1929 et 1945 par Georges Lemaître, fut publié en 1946. Lus aujourd’hui, les textes de ces conférences dressent un tableau de la naissance de la cosmologie moderne. L’ensemble reflète l’évolution rapide des connaissances en astronomie et en physique nucléaire durant la période mouvementée des années 1930 et 1940. De plus, le propos de Lemaître est éloquent par sa finesse pédagogique. Ce petit livre offre un exceptionnel portrait des idées en astronomie et en cosmologie et de leur évolution entre les années 1920 et 1950. Vous assisterez en le lisant à la naissance du big bang.

Although everyone is familiar with the concept of time in everyday life and has probably given thought to the question of how time began, recent scientific developments in this field have not been accessible in a simple understandable form. This book is important as it presents to readers current ideas about the role of time in theoretical cosmology.Recent observational discoveries, especially that the expansion rate of the universe is accelerating, have revolutionized the understanding of the energy content of the universe. This development leads to new possibilities for the beginning and end

""Primordial Cosmology"" deals with one of the most puzzling and fascinating topics debated in modern physics - the nature of the Big Bang singularity. The authors provide a self-consistent and complete treatment of the very early Universe dynamics, passing through a concise discussion of the Standard Cosmological Model, a precise characterization of the role played by the theory of inflation, up to a detailed analysis of the anisotropic and inhomogeneous cosmological models. The most peculiar feature of this book is its uniqueness in treating advanced topics of quantum cosmology with a well-t
