If a black hole is the massively heavy gravity that even light can't escape, then how come we could take some of the first photos of a black hole? (Note: I'm not promoting disbelief in science but rather wanted to see how you guys answer. This question has already been answered by others to me.)

Here's a new blog post on a problem underlying the failures of AI old and new:
https://dblog.vitumbre.tech/dart/failures-of-ai-old-and-new/
There's a lesson to be taken from the failures of attempts to develop AI in the 1960s, '70s, and '80s. The blog post quotes Nick Chater, from his book 'The Mind is Flat' to explain the problem.

THE DOCTOR: To the rational mind, nothing is inexplicable; only unexplained.
LEELA: So explain to me how this “TARDIS” is larger on the inside than the out?
THE DOCTOR: Hmm? All right, I’ll show you. It’s because insides and outsides are not in the same dimension. [holds up two black cubes of different sizes] Which box is larger?
LEELA: [points to the larger of the two] That one.
THE DOCTOR: Alright. [places the larger cube on the console, walks over next to Leela, holds up the smaller one] Now, which is larger?
LEELA: [scoffs, points at the cube on the console] That one!
THE DOCTOR: But it looks smaller.
LEELA: Well, that’s because it’s further away!
THE DOCTOR: Exactly! If you could keep that exactly that distance away, and have it here, the large one would fit inside the small one.
LEELA: That’s silly.
THE DOCTOR: That’s trans-dimensional engineering: a key Time Lord discovery!Doctor Who (1963-1989) British science fiction television series, original run (BBC)

A quotation from Hannah Arendt
Caution in handling generally accepted opinions that claim to explain whole trends of history is especially important for the historian of modern times, because the last century has produced an abundance of ideologies that pretend to be keys to history but are actually nothing but desperate efforts to escape responsibility.
Hannah Arendt (1906-1975) German-American philosopher, political theorist
The Origins of Totalitarianism, Part 1, ch. 1 “Antisemitism as an Outrage to Common Sense” (1951)More about this quote: wist.info/arendt-hannah/46497/

The Generative Excess: Soul, Dream, and Idea
There are three things you cannot show me. You cannot open your hand and reveal your soul. No technology exists to replay your dream from last night with any fidelity. And no surgeon can extract from your skull the moment a thought first assembled itself into an idea. Each of these phenomena exists, if it exists at all, only as a first-person event, invisible to external observation, resistant to measurement, and stubbornly private. That shared inaccessibility is worth taking seriously, because it suggests that the most important operations of human consciousness happen in a place that science can describe from the outside but never enter.
Start with what each one does. The soul, across most Western and Eastern philosophical traditions, answers the question of continuity. It explains why the person who fell asleep last night and the person who woke this morning are the same agent. Whether you locate it in the Aristotelian psyche as the animating form of a living body, or in the Cartesian res cogitans as a thinking substance separate from matter, or in the Hindu atman as an eternal self passing through incarnations, the soul functions as the ground of identity. A dream, by contrast, disrupts continuity. You enter a dream stripped of executive function, unable to recognize logical impossibilities, occupying spaces that shift without transition. You become a spectator inside your own mind, watching a performance you did not commission and cannot direct. A waking idea occupies a third position: it is an act of construction, a moment when the mind assembles discrete elements into a new configuration that did not previously exist. Souls persist. Dreams intrude. Ideas emerge.
That tripartite distinction exposes different relationships to volition. You do not choose to have a soul or to lack one; it is either a feature of your ontological situation or it is a fiction, and in neither case does your preference matter. You do not choose to dream, though the content of dreams appears to draw from waking experience in ways that suggest unconscious editorial selection. J. Allan Hobson’s activation-synthesis hypothesis, proposed in 1977, argued that dreams arise when the brainstem sends random electrical signals during REM sleep and the cortex, desperate to impose order on noise, weaves those signals into narrative. If Hobson was even partially correct, dreaming is the brain telling itself stories to explain its own involuntary electrical activity. A waking idea, however, carries at least the sensation of agency. When Archimedes stepped into his bath and recognized the principle of displacement, or when August Kekulé reported seeing the structure of benzene in a half-waking vision of a snake consuming its own tail, the idea arrived with the force of discovery, as though the thinker had earned it through effort.
Both of those famous examples blur the boundary between dreaming and waking thought. Kekulé’s breakthrough came in a hypnagogic state. Archimedes’ eureka arrived during the kind of relaxed, unfocused attention that resembles dream consciousness more than analytical reasoning. Henri Poincaré described the same experience in his 1908 essay on mathematical creativity: after days of failed conscious effort on Fuchsian functions, the solution arrived unbidden while he was boarding a bus, carrying with it an immediate certainty of correctness. The conscious labor had been necessary, but the synthesis itself happened somewhere else, in a cognitive region that shares more architecture with dreaming than with deliberate calculation. This pattern appears so often in the history of science and art that it demands explanation. The waking mind prepares the ground; the sleeping or distracted mind plants the seed; and the idea appears at the border between the two states, as if consciousness needed to look away before it could see.
All three phenomena involve pattern recognition operating below the threshold of awareness. The soul, if we follow the phenomenological line from Edmund Husserl forward, is the unified field of intentionality that makes pattern recognition possible in the first place. It is the subject that does the recognizing, the “I” that precedes every act of perception. Dreams are pattern recognition run wild, freed from sensory constraint and logical discipline, which is why dream content so often features the recombination of familiar elements into unfamiliar arrangements: your childhood kitchen with the ceiling of a cathedral, a conversation with a dead relative conducted in a language neither of you spoke. An idea, when it arrives, typically feels less like construction and more like recognition, as though the pattern was already present and the thinker merely noticed it. That feeling of discovery rather than invention has troubled epistemologists for centuries, because it implies that ideas have an existence independent of the minds that think them, a position that leads straight to Plato and the theory of Forms, where all knowledge is recollection of truths the soul apprehended before birth.
The differences become sharpest when you examine communicability and persistence. An idea, once formed, can be externalized. You can write it down, speak it, encode it in mathematics or music or architecture, and another person can receive it with reasonable fidelity. Euclid’s geometric proofs remain operative twenty-three centuries later. Darwin’s natural selection survived its author by more than a hundred years and shows no sign of weakening. The idea is the one member of this trio that outlives its host. A dream, however, resists translation. Anyone who has tried to recount a dream knows the experience of watching its internal logic evaporate in the telling. The narrative that felt saturated with meaning at 3 a.m. becomes, by breakfast, a string of non-sequiturs that embarrass the teller. Dreams are experiences that degrade upon export; their meaning, if they have meaning, may be inseparable from the neurochemical state that produced them. The soul occupies the most isolated position of all. You can describe your beliefs about the soul, argue for its existence or its absence, construct elaborate theological frameworks around it, but you cannot transmit the thing itself. If the soul is real, it is the most private object in existence, the one possession that cannot be shared, stolen, or photographed.
I want to take a position on truth-value here rather than retreat into academic equivocation. A waking idea can be tested. It can be wrong, and its wrongness can be demonstrated. Kekulé’s benzene ring was either an accurate model of molecular structure or it was a fantasy, and subsequent X-ray crystallography confirmed the model. Ideas submit to verification, and that submission is what gives them their power and their danger. Dreams make no truth claims and therefore cannot be falsified; they operate in a space where contradiction is a feature rather than a defect, where you can be simultaneously yourself and someone else, where gravity applies in one room and not the next. The soul occupies the most precarious epistemic position of the three, because it asserts an enormous truth claim (that personal identity has a metaphysical ground, that you are more than your biology) while offering no mechanism for verification. This is why the soul has migrated over the past four centuries from philosophy into theology: it requires faith in a way that ideas and dreams do not.
Yet there is a way to read all three as expressions of a single underlying capacity. Call it generative excess. A soul posits a self that is more than the sum of its biological processes. Dreams generate entire worlds from stored fragments without any current sensory data. An idea produces a new structure from existing elements that, in their previous arrangement, did not suggest that structure. In each case, something appears that was not contained in its antecedents. The mind, whether sleeping or waking, whether reflecting on its own nature or assembling a new theorem, keeps producing more than its inputs would predict. Whether you call that capacity consciousness, emergence, or grace depends on your commitments, but the surplus is common to all three phenomena. Differences among the three lie in duration, controllability, and communicability. Souls endure, or claim to. Ideas can be transmitted. Dreams do neither, and perhaps that is why, of the three, dreaming remains the most mysterious and the least respected, despite being the one phenomenon whose existence no one disputes.
What holds these three together is the stubborn fact that the human mind refuses to be merely reactive. It insists on generating experience that exceeds what the world hands it. That insistence may be our defining characteristic as a species, and it may also be our greatest vulnerability, because a mind that generates more than it receives is a mind that can deceive itself with its own productions. The soul may be one such self-deception. The dream is a nightly demonstration of how persuasive such deceptions can be. And the idea, when it is wrong, can lead entire civilizations into error. The generative excess gives us Euclid’s geometry and astrology, penicillin and phrenology, cathedral architecture and conspiracy theories. The capacity itself is neutral; what matters is whether we can distinguish its products from its illusions. That question has occupied philosophy since Socrates, and we are no closer to settling it now than we were in Athens. The soul, the dream, and the idea all emerge from the same restless source, and the fact that we cannot see that source directly may be the most important thing about it.

Dear sire, and offspring worthy of your fire!
We bards are dupes to what ourselves admire.
Would I be brief — I grow confused and coarse;
Who aims at smoothness, fails in fire and force;
In him who soars aloft, bombast is found;
Who fears to face the tempest, crawls aground.
Who courts variety and fain would ring
A thousand changes on the self-same string,
Will paint, as ’twere in fancy’s wildest mood
Boars in the wave and dolphins in the wood.
Thus even error, shun’d without address,
Breeds error, diff’rent in its kind, not less.
[Maxima pars vatum, pater et iuvenes patre digni,
decipimur specie recti: brevis esse laboro,
obscurus fio; sectantem levia nervi
deficiunt animique; professus grandia turget;
serpit humi tutus nimium timidusque procellae:
qui variare cupit rem prodigialiter unam,
delphinum silvis adpingit, fluctibus aprum:
in vitium ducit culpae fuga, si caret arte.]Horace (65–8 BC) Roman poet, satirist, soldier, politician [Quintus Horatius Flaccus]

A note on #explanation and #understanding (and a likely limitation on the possibility of LLMs providing genuine #PersonalisedLearning )
tl;dr - A more effective explanation is not just a reformulation of a less effective one, it involves working out what was taken to be obvious (to the explainer) but isn't (to the explainee)

A quotation from Arthur Conan Doyle
I’m not going to tell you much more of the case, Doctor. You know a conjurer gets no credit once he has explained his trick; and if I show you too much of my method of working, you will come to the conclusion that I am a very ordinary individual after all.
