Even though I liked the article it didn't mean I didn't like the movie. I think Interstellar is a better movie than most films because at least they tried to incorporate some true science into it (as opposed to 100% wrong movies like armageddon, sunshine, etc). So Nolan, Kipp, et al definitely do get the credit for that!
That scene was obviously not trying to be rigidly scientific. Either he died and what followed was his death dream, or the hyper advanced civilization that can control gravity manipulated the black hole so he could survive. Technology looks like magic to the unknowing.
