The deepest things we don't yet understand.

A step-by-step account of how a memory gets written and read back, at the level of molecules and synapses, that explains what we've actually seen in people: why memories fade, why a smell can pull back a whole scene, why some things stick after one exposure and others never do, and why a memory changes a little every time you recall it.

One unbroken chain that starts with ions and voltage, climbs through firing neurons and networks, and ends in the felt experience of tasting the food again, with no unexplained jump between the physical steps and the moment it becomes something you feel.

A decoding rule that maps specific spike patterns to specific mental content, checked against real recordings, sharp enough to read a thought off the activity and predict how the activity shifts when the thought shifts.

A mechanism for why sight, sound, touch, and self arrive as a single fused "now" instead of separate streams, that also explains what breaks the binding in seizures, anesthesia, and split-brain patients.

The precise molecular and network change that removes experience while the brain stays alive and firing, sharp enough to name the property that, once present, makes consciousness appear, and once removed, makes it vanish.

The core job sleep does that nothing else can, precise enough to explain what builds up in a waking brain that only sleep clears, and why evolution kept animals helpless for hours despite the obvious danger.

The developmental program from single cell to wired brain, spelling out how neurons find their targets, how much is written in the genes versus shaped by experience, and why the same program yields a working mind almost every time.

A mechanism that settles whether forgetting is passive decay, interference, or active erasure, and explains why we lose so much yet keep exactly what matters, and why some memories refuse to fade no matter how hard we try.

An account of what starts a self-generated thought in the physical brain, why the mind wanders even at rest instead of going quiet, and what decides which thought surfaces next.

The rule that turns a one-dimensional gene sequence into a precise three-dimensional shape, explaining how cells know their position, why a hand gets exactly five fingers, and what signal says "stop growing here."

A physical account of how a floppy chain finds its one working shape almost instantly out of astronomically many options, precise enough to predict the fold and to explain what goes wrong in the diseases where folding fails.

The decision logic a cell runs on, traced from the chemical signals it reads to the choice it makes, sharp enough to explain why the same cell divides in one context and kills itself in another.

A single frame that explains why cancer keeps arising across almost every species and tissue, why it looks like coordinated behavior rather than random breakage, and what would actually have to be true to stop it at the root.

The mechanism that lets a body attack nearly any invader it has never seen while sparing its own cells, explaining how the line is learned, and why it fails in autoimmune disease and in cancers that hide.

A causal account of what aging actually is, precise enough to say whether it is a clock the body runs on purpose or wear that piles up, and to predict what would happen if you removed the primary cause.

The reason some animals rebuild whole body parts and we cannot, traced to what their cells do differently, and whether that capacity is switched off in us or was never there to switch on.

A plausible route from ordinary molecules to the first self-copying system, with the actual steps and conditions, that explains how information and metabolism started together rather than one waiting on the other.

An explanation for why life settled on this specific mapping of codons to amino acids, whether it was frozen accident or forced by chemistry, and why nearly everything alive still shares it.

The reason biology picked one handedness and stuck with it universally, tracing whether the choice was random and then locked in, or driven by some real physical bias present at the start.

An account of whether everything alive traces to a single origin, backed by what the shared machinery of all cells implies, and an honest estimate of how probable life is given the same starting conditions.

A single framework that holds where both matter, like the center of a black hole and the first instant, making predictions we could in principle test, not just a story about why the two current theories disagree.

A clear account of what a measurement is and why we see one outcome when the math allows many, sharp enough to say whether collapse is a real physical event or an artifact of leaving something out.

The identity of the stuff that outweighs everything we can see, whether particle or something stranger, that explains why galaxies hold together and matches what we observe without inventing a new fix for each case.

An account of what is accelerating the expansion of the universe, why its measured strength is so far from what theory predicts, and what its behavior implies for how everything ends.

The mechanism that left a universe of matter when the beginning should have made equal antimatter, precise enough to point at the specific asymmetry and, ideally, to something we could measure.

A resolution of what happens to matter and to information at the center and at the end of a black hole, that keeps physics consistent instead of quietly destroying information the rest of physics says can't be destroyed.

An explanation for why we remember the past and not the future, and why things break but never unbreak, grounded in why the universe began in such a low-entropy state in the first place.

An account of whether spacetime is a bedrock feature of reality or a large-scale appearance of something more basic, sharp enough to say what that deeper thing is and how smooth space arises from it.

A physical account of the earliest moment that doesn't hide behind a singularity, addressing whether "before" is even a coherent question and what, if anything, set the initial conditions.

An explanation for why the numbers governing physics sit in the narrow band that allows atoms, stars, and life, that does real work rather than shrugging at coincidence or leaning on unobservable other universes.

An honest account of whether space goes on forever or closes back on itself, what evidence could ever settle it, and what it would mean for how much exists beyond what we can see.

A grounded estimate of how often life arises given the conditions, that squares the size and age of the universe with the fact that we've heard nothing, and says which of the possible explanations the evidence favors.

A settled answer to whether every problem whose solution is quick to verify is also quick to solve, and a clear account of what it would mean for cryptography, science, and creativity if the two turned out to be the same.

A proof of the deep pattern behind where primes fall, precise enough to explain why they look random up close yet follow a strict law in bulk, and what that hidden order connects to elsewhere in math.

A proof, one way or the other, that the equations we use for water and air always give sensible answers, or a case where they break, and an explanation of what a breakdown would mean physically.

A defensible position on whether mathematical truths exist independently of us or are made by us, that accounts for why abstract math so often turns out to describe the physical world decades before anyone needs it.

A first-principles account of water's long list of anomalies, from ice floating to its strange density, traced to the molecular behavior behind them, and why life depends on exactly those oddities.

A method that goes from the fundamental equations to what a molecule will actually do, accurately and at useful scale, so we can design a material or a drug on a screen and have it work in the world.

A theory of turbulent flow that predicts its structure from the governing equations, explaining why a problem with no quantum mystery has stayed unsolved for over a century.

An account of how living order builds and sustains itself against the pull toward equilibrium, precise about what makes matter organize this way and whether it was likely or rare.

An explanation for why physical processes in a brain are accompanied by inner experience at all, that closes the gap between describing what the brain does and why there's something it is like to be it.

A verdict on whether the feeling of being the author of your actions reflects real causal control or a story the brain tells after the fact, grounded in what experiments on choice and timing actually show.

A criterion that separates genuine understanding from convincing imitation, sharp enough to apply to both a person and a machine, and to say whether how it works underneath changes the answer.

A test for the presence of experience in something unlike us, an animal, an AI, a patient who can't respond, that doesn't just measure behavior, plus an honest account of why the problem may be this hard.

An argument for whether experience can be captured in a precise theory that predicts which systems are conscious and how much, or a real reason it lies permanently outside what formal description can reach.

A workable standard for explanatory quality, beyond fitting the data, that captures why a hard-to-vary explanation beats a flexible one, and could actually be used to rank rival theories.

A principled line between problems that are merely unsolved and ones that are unsolvable in principle, with a way to tell which side a given question falls on before we waste centuries on it.

A method for checking whether a claim is true that holds up against a smarter adversary trying to fool it, robust enough to work when the thing being checked is more capable than the checker.

An account of which bottleneck actually slows progress now, ignorance or well-packaged error, and what changes about how we should filter information if the second one dominates.

A practical answer for how to live, judge, and hold people responsible once you take the mechanistic picture seriously, that doesn't collapse into either denial or fatalism.

A realistic ceiling on personal change, backed by what we know about temperament, habit, and identity, that separates the traits that actually move from the ones that only seem to.

An account of what, if anything, stays constant and makes you one continuous self from childhood to old age, when nearly every cell, memory, and belief has turned over.

A source of meaning that survives the end of work as the default life structure, concrete enough to say how the roughly one in ten thousand who already live this way could become the many.

A usable model of how difficulty forms character, precise enough to find the line where struggle strengthens someone versus where it does lasting damage, and how it differs across people.

An alternative yardstick for a life well lived once external markers lose their grip, that holds up against the pull of comparison and gives a real answer to "was it enough."

A clean distinction between AI that does the work of general intelligence and AI that is generally intelligent in some deeper sense, and an argument for which one actually reshapes the world, and when.

A short list of concrete, hard-to-fake signals that would tell us AGI has arrived rather than been hyped, specific enough that we'd recognize the moment while it's happening instead of years later.

A grounded account of whether machine experience is possible, what would have to be true for it, and what evidence would move us, given that the systems can already claim anything we train them to say.

A view of what intelligence ultimately does in the universe, whether it's a local accident or plays some larger role against disorder, that says something testable rather than merely poetic.

An account of whether a copied or uploaded mind is still you or just a convincing stranger with your memories, sharp about what continuity of self actually requires, and whether the goal even makes sense.

A serious treatment of whether our reality is computed, what observable cracks a simulation might leave, and whether the question can be settled at all or only argued in circles.

An explanation for why anything exists at all instead of a blank, that gets past restating the puzzle and says whether "nothing" was ever a real option or just a word we can form.
