A phenomenological relativity book, in the level of first year of master degree, or last year of B.Sc in theoretical physics. broad examples and practical applications with actual experiments results. latest edition which I studied, has updates for new or near future tests or observatories.
It could be better, theoretically, but still good book. If I want to bring readers an example, its ancestors are, Gravitation by Wheeler, Thorne, Misner. But not Hawking-Penrose, large scales and R. Wald, G.R. these two books which second one is a new version of the first are pure theoretical and if someone looks for topology in older books these are the ones. Of course H-P book, is based on Gravitation which for the first time topology, practical general relativity and phenomenology tried to introduce a new face of difficult mathematical physics of GR.
In astrophysics we have B. Carroll (orange book) in the same level and method of teaching (Just as a comparison).
