Introduction I do not conclude that black holes being a mathematical singularity is the same thing as saying the black hole is a singularity. The notion of information being lost in a black hole is a necessary truism perhaps because the observer cannot tell the difference. Within the black hole, there is structure that can affect the observation from the outside. That is information within the black hole may change the shape of the black hole in such a way that information can escape. From Wikipedia: A black hole is a region of spacetime exhibiting such strong gravitational effects that nothing—not even particles and electromagnetic radiation such as light—can escape from inside it. The definition of a black hole rests on the effects of the observer to witness what is occurring within, which is that light and particles cannot escape at the time of the observation. This is not the same thing as what is in the black hole. Thought When two si...
