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.
Robitzski: “It suggests our entire universe might just look like any other tiny black hole bubble to an outside observer.”
Physicist: You see, the black hole isn’t just eating matter and belching radiation, it is reversing entropy. This shouldn’t be possible.
Classically, it shouldn’t have happened.
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.
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.
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?
It all sounds so much like religion, actually, but maybe that’s the direction in which High Science is heading.
Can’t help but make one wonder how much else in popular science literature is wrong but sells books.
Dvorsky: Astronomers are puzzling over observations that show a black hole smashing into a mystery object of unusual size.
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.
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. 😉
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. “
Researcher: “We cannot understand the data unless we include the theories of relativity.” …
Her view: Most physicists believe that the solution is that the Hawking radiation somehow must contain information after all.
