An Introduction to Relativistic Gravity
The standard world models which are used as the framework for astrophysical cosmology and for studying the problems of galaxy formation are based upon Einstein’s General Theory of Relativity. General Relativity is a beautiful theory but it requires a thorough understanding of tensor calculus in four-dimensional non-Euclidean spaces to appreciate Einstein’s epoch-making achievement. Since this is beyond the scope of the present text, Sects. 6.1 to 6.5 are intended to provide some flavour of the full theory and to introduce some key ideas which will be needed later. In Sect. 6.6, the current status of General Relativity is surveyed and it is shown that it is the best relativistic theory of gravity we possess. If you are happy to accept General Relativity at its face value, you may advance to Chap. 7.
