The Universe of General Relativity
Outgrowth of 6th Int'l Conference on the History of General Relativity, held in Amsterdam on June 26-29, 2002 Contributions from notable experts offer both new and historical insights on gravitation, general relativity, cosmology, unified field theory, and the history of science Topics run gamet from detailed mathematical discussions to more personal recollections of relativity as seen through the eyes of the public and renowned relativists
Gravity, Particles, and Astrophysics
This book deals with the relationship between gravitation and elementary particle physics, and the implications of these subjects for astrophysics. There has, in recent years, been renewed interest in theories that connect up gravitation and particle physics, and in the astrophysical consequences of such theories. Some of these accounts involve a time-variation of the Newtonian gravitational parameter, G. In this respect, the present book may be regarded as a companion to my Cosmology and Geophysics (Hilger, Bristol, 1978). There is some overlap as regards the discussion of G-variability, but the emphasis in the present book is on astrophysics while the emphasis in the other one is on geophy...
Relativistic Models of the Universe with Pressure Equal to Zero and Time-dependent Uniformity
The previous work on the zero-density and approximate models of the universe, published in NASA TN D-3047, is summarized. The zero-density model is improved so that it is a useful approximation of the exact model to greater values of the red shift, and regions of applicability of the approximate model are determined. Regions where closed-form solutions of the exact model exist, other than zero-density and zero-cosmical-constant models, are defined and the solutions are given. The results of calculations are presented that indicate, for the data considered, all the models, simplified and exact, appear to fit the data equally well even though there is wide variation in the density and acceleration parameters. In addition, the results of the calculations indicate that density and acceleration parameters should be determined as a pair from observational data. It is concluded that data consistent with that for galaxies at red shifts greater than one-half are required before a model universe can be selected and a simplified model defined.

The Deep Universe
Written by three celebrated astronomers renowned for their excellence in both research and teaching, the central theme is approached in three complementary ways: the smooth evolution of the universe from the Big Bang to the present structures of matter; as a meandering road paved by our observations of stars, galaxies, and clusters; and how these approaches have been gradually developed and intertwined in the historical process leading to modern-day cosmology.
