About gravity and the concept of gravity as Albert Einstein saw it- curved spaces, four-dimensional manifolds and geodesics. The book starts with the 1st principles of relativity and an introduction to Einstein's field equations. Next up are the three classical tests of the relativity theory and an introduction to black holes. The book contains several topics such as Kaluza-Klein theory, anisotropic models of the universe, and new developments involving brane cosmology.Gron and Hervik have included a part in the book called Advanced Topics. These topics range from the very edge of research to older, accepted ideas. In particular, the last two chapters deal with Einstein gravity in five dimensions, which has been a hot topic of research in recent years. «
