We have today given a presentation at IU Science Slam with the same title as this post. The main themes are to present the black hole theory derived from Einstein’s General Relativity, and to point out the essential differences between the black hole theory and the viewpoint on black holes from Newton’s Law. The final message is
nothing gets out of the black hole, and nothing gets inside a black hole either.
This is based on a recent paper [Tian Ma & Shouhong Wang, Astrophysical dynamics and cosmology, J. Math. Study, 47:4 (2014), 305-378]; see also the previous blog post: Singularity at the Black-Hole Horizon is Physical.
