A new solution for Hawking’s black hole paradox? “Quantum hair”

Catchy, we gotta admit:

In 1976, Hawking suggested that, as black holes evaporate, they destroy information about what had formed them.

That idea goes against a fundamental law of quantum mechanics which states any process in physics can be mathematically reversed.

In the 1960s, physicist John Archibald Wheeler, discussing black holes’ lack of observable features beyond their total mass, spin, and charge, coined the phrase “black holes have no hair”—known as the no-hair theorem.

However, the newly discovered “quantum hair” provides a way for information to be preserved as a black hole collapses and, as such, resolves one of modern science’s most famous quandaries, experts say.

Prof Calmet said: “Black holes have long been considered the perfect laboratory to study how to merge Einstein’s theory of general relativity with quantum mechanics.

“It was generally assumed within the scientific community that resolving this paradox would require a huge paradigm shift in physics, forcing the potential reformulation of either quantum mechanics or general relativity.

“What we found—and I think is particularly exciting—is that this isn’t necessary.”

“Scientists may have solved Stephen Hawking’s black hole paradox” at Phys.org (March 18, 2022)

Here’s a puff piece for the idea:

Let’s wait and see. Our favorite line from the media release: “In the first paper, published in the journal Physical Review Letters, researchers demonstrated that black holes are more complex than originally thought and have gravitational fields that hold information about how they were formed.”

Where, oh, where have we heard the signature tune “more complex than originally thought”? Funny how the universe in general is not devolving down into a few simple “nothing” principles …

Both the Physics Letters B paper and the Physical Review Letters paper are open access.

    Are we to conclude that DI and IDers are laying claim to the phrase “more complex than originally thought?” Perhaps DI should attempt to copyright it and see how far it gets…..

    No, that’s not what was meant by that comment. IDers have all heard that signature tune many times. It’s not one of ours and we don’t need or want a copyright on it. The people who thought nature would be simple are the ones who have to keep singing that line. The followers of the guy who thought a bear could turn into a whale by opening it’s mouth wider, and the followers of the guy who thought the cell was a primitive blob of protoplasm that could easily evolve new biological functions – they’re the ones who are the one-hit wonders of our day. Everything “is more complex than originally thought” la, la, la
    It’s not a very good tune at all.

    Chuckdarwin, as Silver Asiatic pointed out, “IDers have all heard that signature tune many times. It’s not one of ours (its yours) and we don’t need or want a copyright on it.”

    For instance, “the brain’s complexity is beyond anything they’d imagined, almost to the point of being beyond belief”

    Human brain has more switches than all computers on Earth – November 2010
    Excerpt: They found that the brain’s complexity is beyond anything they’d imagined, almost to the point of being beyond belief, says Stephen Smith, a professor of molecular and cellular physiology and senior author of the paper describing the study: …One (neuronal) synapse, by itself, is more like a microprocessor–with both memory-storage and information-processing elements–than a mere on/off switch. In fact, one synapse may contain on the order of 1,000 molecular-scale switches. A single human brain has more switches than all the computers and routers and Internet connections on Earth.

    And, “a world we had never imagined.”

    Brain Architecture: Scientists Discover 11 Dimensional Structures That Could Help Us Understand How the Brain Works – Hannah Osborne – 6/12/17
    Excerpt: Scientists studying the brain have discovered that the organ operates on up to 11 different dimensions, creating multiverse-like structures that are “a world we had never imagined.”

    And, “it is like comparing different degrees of infinity.”

    Systems biology: Untangling the protein web – July 2009
    Excerpt: Vidal thinks that technological improvements — especially in nanotechnology, to generate more data, and microscopy, to explore interaction inside cells, along with increased computer power — are required to push systems biology forward. “Combine all this and you can start to think that maybe some of the information flow can be captured,” he says. But when it comes to figuring out the best way to explore information flow in cells, Tyers jokes that it is like comparing different degrees of infinity. “The interesting point coming out of all these studies is how complex these systems are — the different feedback loops and how they cross-regulate each other and adapt to perturbations are only just becoming apparent,” he says. “The simple pathway models are a gross oversimplification of what is actually happening.”

    and etc.. etc.. etc..,

    Moreover, contrary to the Darwinian belief of “biological mechanisms, (being), an historical record of evolutionary and developmental compromises”

    William Bialek is the John Archibald Wheeler/Battelle Professor in Physics at Princeton University. Excerpt: While it is popular to view biological mechanisms as an historical record of evolutionary and developmental compromises, these observations on functional performance point toward a very different view of life as having selected a set of near optimal mechanisms for its most crucial tasks.
    https://www.princeton.edu/~wbialek/wbialek.html

    instead of ‘evolutionary compromises’, we instead find that, “In each instance, biophysicists have calculated, the (biological) system couldn’t get faster, more sensitive or more efficient without first relocating to an alternate universe with alternate physical constants.”

    William Bialek: More Perfect Than We Imagined – 2013
    Excerpt: Scientists have identified and mathematically anatomized an array of cases where optimization has left its fastidious mark, among them the superb efficiency with which bacterial cells will close in on a food source; the precision response in a fruit fly embryo to contouring molecules that help distinguish tail from head; and the way a shark can find its prey by measuring micro-fluxes of electricity in the water a tremulous millionth of a volt strong — which, as Douglas Fields observed in Scientific American, is like detecting an electrical field generated by a standard AA battery “with one pole dipped in the Long Island Sound and the other pole in waters of Jacksonville, Fla.” In each instance, biophysicists have calculated, the system couldn’t get faster, more sensitive or more efficient without first relocating to an alternate universe with alternate physical constants.

    So ChuckyD, again, “IDers have all heard that signature tune many times. It’s not one of ours (its yours) and we don’t need or want a copyright on it.”

    In short, it is the (‘beyond belief’) evidence coming from molecular biology itself, and the words that (supposedly Darwinian) researchers themselves are using to describe that (beyond belief) evidence, that is betraying your Darwinian religion, not anything in particular that ID advocates may be doing, or saying, that is betraying your Darwinian religion.

    Psalm 139:13-14
    For You formed my inmost being; You knit me together in my mother’s womb. I praise You, for I am fearfully and wonderfully made. Marvelous are Your works, and I know this very well.

    Perhaps superstring theory is almost right.

    “Perhaps superstring theory is almost right.”

    via the title of Peter Woit’s blog, it is ‘Not Even Wrong’
    https://www.math.columbia.edu/~woit/wordpress/

    Of note:

    “Not even wrong” is a phrase often used to describe pseudoscience or bad science.[1] It describes an argument or explanation that purports to be scientific but uses faulty reasoning or speculative premises, which can be neither affirmed nor denied and thus cannot be discussed rigorously and scientifically.[1],,,
    The phrase is generally attributed to the theoretical physicist Wolfgang Pauli, who was known for his colorful objections to incorrect or careless thinking.[2][3] Rudolf Peierls documents an instance in which “a friend showed Pauli the paper of a young physicist which he suspected was not of great value but on which he wanted Pauli’s views. Pauli remarked sadly, ‘It is not even wrong’.”[4][5]
