Michael Egnor: Both an intelligent designer (assuming we’re talking about God) and a black hole are supernatural, in the sense that they are not objects in the natural world. This may not surprise you about God, but it is also true of black holes.

Researchers: Black holes are collapsed universes
Robitzski: “It suggests our entire universe might just look like any other tiny black hole bubble to an outside observer.”
Will black holes really break physics?
Physicist: You see, the black hole isn’t just eating matter and belching radiation, it is reversing entropy. This shouldn’t be possible.
A recent black hole collision has spurred thinking about the tiniest scales
Classically, it shouldn’t have happened.
Sabine Hossenfelder: The black hole information problem is not solvable
Hossenfelder: Today I comment on the recent claim that the black hole information loss problem is “near its end” and explain why this is nonsense.
At Forbes: Hawking’s black hole paradox is NOT solved
Ethan Siegel looks at the limitations: But we’re still a long way away from determining exactly where that information goes, and how it gets out of a black hole. Theorists disagree over the validity and soundness of many of the methods that are currently being employed to do these calculations, and no one has even a theoretical prediction for how this information should be encoded by an evaporating black hole, much less how to measure it.
Did the black hole paradox really come to an end? Rob Sheldon offers some thoughts
Sheldon: Black Holes are a theoretical and empirical disaster. Given two possible assumptions to Schwarzschild’s solution of Einstein’s gravity equation, nearly everyone has taken the discontinuous, unphysical, “event-horizon” assumption leading to “Black Holes”. One of the many predictions of BH, is that they cannot have magnetic fields, and they destroy anything that falls into them, converting all that matter into “Hawking radiation”. What about all that data showing high density objects at the center of our galaxy and neighboring galaxies?
Roger Penrose thinks black holes are left over from a previous universe
It all sounds so much like religion, actually, but maybe that’s the direction in which High Science is heading.
At Forbes: Claim that Stephen Hawking “lied” about black holes
Can’t help but make one wonder how much else in popular science literature is wrong but sells books.
At Gizmodo: A black hole collides with something that “shouldn’t exist”?
Dvorsky: Astronomers are puzzling over observations that show a black hole smashing into a mystery object of unusual size.
Black holes are—no surprise—full of surprises
At Quanta: In the latest surprise, that link turns out to exemplify a general fact about nature. In a paper published in March in Physical Review Letters, Goon and Riccardo Penco broadened the lessons of the earlier work by proving a simple, universal formula relating energy and entropy. The newfound formula applies to a system such as a gas as well as a black hole.
At Quanta: How gravity differs from the other three fundamental forces
Your experiment to get to the bottom of gravity collapses into a black hole? Well, that’s just gravity’s way of declining an interview. Suck it up. 😉
Researchers: No, you can’t escape a black hole
Why not?: “The group found that for both types of black holes they examined, there is indeed a central singularity, and it is always spacelike. “
A black hole that just shouldn’t exist
Researcher: “We cannot understand the data unless we include the theories of relativity.” …
Sabine Hossenfelder: Black holes vs. quantum mechanics = something has to give
Her view: Most physicists believe that the solution is that the Hawking radiation somehow must contain information after all.
