hi recently i attended a lecture where a current researcher from my university was talking about black holes and the schwarzchild metric. basically he was saying no current theory predicts black holes and the schwarzchild solution is not actually correct, his solution was accepted because apparently he was a highly influential mathematician. he said that the r term in the schwarzchild metric should actually be r->(r^3+a^3)^(1/3) where a = 2GM/c^2 as you see the a term is quite small (G=gravitation constant and c is the speed of light). my understanding of the majority of his talk was a bit shakey but he didnt seem like a nut as there were a few other professors attending the lecture also and they couldnt point out any flaws in his argument. he reckons that no one else has pointed this mistake out yet and has submitted his report to be published in a journal.
