Thanks I guess. Although do note that Black hole is not "my" article, since nobody owns a wikipedia article. Also, although I have put a lot of work into that article, many other editors have contributed to that article as well, and also deserve credit for their work. Unfortunately for you, I haven't written any books. Learning about GR, without much mathematical or physical background, can be quite hard, since it requires some pretty abstract concepts to make precise. If you do have some background knowledge, then Carroll's book (or lecture notes, see reference in the black hole article) is really good, finding a really good balance between mathematical clarity and physical intuition, while referring to sources that give more in depth treatment of subjects that he skims over.R
