Relativistic cosmology has in recent years become one of the most active and exciting branches of research, often considered to be today where particle physics was forty years ago, with major discoveries just waiting to happen. Consequently the part most affected by this second edition is the last part on cosmology. But there are additions, improvements, and new exercises throughout. _ The book's basic purpose is unchanged. It is to make relativity come alive conceptually, and to display the grand theoretical edifice that it is, with consequences in many branches of physics. The emphasis is on the foundations, on the logical subtleties, and on presenting the necessary mathematics - including differential geometry and tensors - but always as late and in as palatable a form as possible. Aided by over 300 exercises, the book seeks to promote an in-depth understanding, and the confidence to tackle any basic problem in relativity.

Relativistic cosmology has in recent years become one of the most exciting and active branches of current research. In conference after conference the view is expressed that cosmology today is where particle physics was forty years ago, with major discoveries just waiting to happen. Also gravitational wave detectors, presently under construction or in the testing phase, promise to open up an entirely novel field of physics. It is to take into account such recent developments, as well as to improve the basic text, that this second edition has been undertaken. The most affected is the last part on cosmology, but there are smaller additions, corrections, and additional exercises throughout. The books basic purpose is to make relativity come alive conceptually. Hence the emphasis on the foundations and the logical subtleties rather than on the mathematics or the detailed experiments per se. Aided by some 300 exercises, the book promotes a deep understanding and the confidence to tackle any fundamental relativistic problem.
