general relativity - Black Holes can't exist?

So in this article here, Mersini-Houghton says that Black Holes can't exist. Is there any truth to this?

Answer

The idea that black holes can't exist goes against the mainstream viewpoint, and also goes against observational evidence. See the Observational evidence section of Wikipedia's Black hole article.

There would need to be independent corroborative papers published in peer-reviewed journals for this to hold up. Mersini-Houghton's earlier paper in Physics Letters B counts, but arXiv isn't peer-reviewed, so her more recent paper that was only "published" in arXiv doesn't count for much.
