FIELDS MEDALIST TESTED IF HE'S OBSOLETE timothy gowers took an open problem from a new paper on additive combinatorics and handed it to chatgpt 5.5 pro. no fancy prompts. no setup. just the problem statement. the model thought for 17 minutes. then wrote a complete latex preprint in two. it took a bound that had been exponential for decades and brought it down to polynomial. the construction was something nobody had tried on this class of problems before. gowers asked isaac rajagopal to review the work. rajagopal wrote the paper the model was improving on. his verdict: the key idea is "completely original" and "quite ingenious." "the sort of idea i would be very proud to come up with after a week or two of pondering." the model spent 17 minutes on it. then gowers pushed further. gave it the harder generalized version. under an hour, a stronger result. exponential to polynomial again. gowers on his own mathematical contribution to the whole thing: "zero. i didn't even do anything clever with the prompts." the result is a solid chapter in a combinatorics phd. publishable mathematics that a graduate student would spend months producing. a fields medalist. one of the best combinatorialists alive. sitting there copy-pasting prompts while a model does doctoral-level research in front of him. his conclusion: "the lower bound for contributing to mathematics will now be to prove something that llms can't prove." he gives the profession until 2029 before it's "transformed out of all recognition." seventeen minutes. zero human math. a result that takes months by hand. this was may 2026. five months ago. the model that did it is already outdated. link to the paper in the comments

THIRD KIND OF MAGNET manganese telluride has been sitting in labs for decades. routine material, well-studied, nothing special. turns out it belongs to a completely new class of magnets that nobody knew existed until three years ago. for over a century the textbook said there are two kinds of ordered magnets. ferromagnets: spins line up, net magnetization, this is your fridge magnet and your hard drive. antiferromagnets: neighboring spins point opposite ways, cancel out, no net magnetization, fast dynamics but hard to read electrically. in 2022 three theorists published a symmetry classification showing there is a third option. in altermagnets the spins still cancel out in real space, just like in antiferromagnets. but the crystal structure rotates the two spin sublattices relative to each other so that in momentum space the bands split by spin. that is something only ferromagnets were supposed to do. you get the stability of an antiferromagnet and the electrical readability of a ferromagnet in the same crystal. plus terahertz switching speeds. the combination was not supposed to exist. the reason nobody caught this earlier is surprisingly mundane. the standard symmetry framework for magnetic materials lumped altermagnets in with ordinary antiferromagnets. the team had to build a new spin-group theory that separates spin symmetry from crystal symmetry. once you look through the right lens, hundreds of known materials turn out to be altermagnets. confirmation came fast. in early 2024, photoemission spectroscopy on manganese telluride showed exactly the spin splitting the theory predicted. published in Nature. weeks later, chromium antimonide showed the same signature. Science magazine named it a top breakthrough of 2024, the only physics entry on their list. in july 2026 the European Physical Society awarded the Europhysics Prize to Smejkal, Sinova, and Jungwirth for the discovery. the practical interest is spintronics: memory and sensors that combine what ferromagnets and antiferromagnets do separately. but i think the more interesting part is that we had these crystals for decades, measured them many times, and missed what they were. because the categories we used to sort magnets were incomplete. link to the paper in the comments

AI DESIGNS THE NEXT PARTICLE COLLIDER three hundred physicists and engineers just signed a document saying the next particle collider should be designed by artificial intelligence from the ground up. the whole machine. magnets, detectors, beam optics, control systems. all co-designed with neural networks before a single component is built. two papers came out of US national labs almost the same week in february. one lays out a vision of a "fully autonomous accelerator." a machine that tunes its own beam, diagnoses faults, and adapts to whatever experiment physicists want to run next. the other, backed by the American Physical Society, puts numbers on the ambition: cut downtime by half, calibrate ten times faster, reduce the effort of data analysis by a factor of a thousand. i went through both papers. the honest part: neither one contains a new experimental result. these are roadmaps. the numbers they cite are goals, and nobody knows yet if they are realistic. but individual pieces already work, and some have been running for years. > reinforcement learning steers beams through CERN's accelerator chain > neural networks classify faults in superconducting cavities at Jefferson Lab in real time > at Brookhaven, ML kept the old RHIC beams as stable as a human operator could > an LLM-based system called Osprey monitors the Advanced Light Source in Berkeley each of these solves one narrow problem. the gap between "AI tunes one magnet" and "AI designs and operates an entire collider" is enormous. roughly the distance between spell-check and writing a novel. the first real test is already under construction. the Electron-Ion Collider at Brookhaven will be the first major accelerator with AI in the design loop from day one. bayesian optimization picks detector geometry. a digital twin mirrors the beam in real time. half a million collisions per second will need machine learning just to keep up with the data stream. the estimated bill for the AI workforce alone is around forty million dollars a year over five years. both papers openly admit they have no solutions to most of the hard problems. the whole point of a manifesto like this is to lock in funding and talent before anyone knows whether full autonomy is achievable. for big physics this is standard practice. you declare the destination, then spend a decade figuring out the road. in this case most of the road still needs to be invented. link to the paper in the comments

DARK ENERGY MIGHT BE A SIDE EFFECT OF QUANTUM GRAVITY two of the biggest open problems in physics have been treated as separate for decades. dark energy, the thing accelerating the expansion of the universe. quantum gravity, the missing theory that reconciles relativity with quantum mechanics. most physicists work on them independently. ginestra bianconi at queen mary university of london wrote a framework where they are the same problem. she treats the spacetime metric as a quantum operator and builds the gravitational action from the quantum relative entropy between two metrics. one from geometry, one from matter fields. gravity becomes an information gap between the two. at low energies the equations reduce to general relativity. at stronger curvature they produce a small positive cosmological constant. dark energy emerges from the quantum structure of spacetime without being put into the equations by hand. the same framework generates a G-field that behaves gravitationally like dark matter. > original paper: Physical Review D, 2024 > thermodynamics follow-up: Physical Review D, > july 2026 > group field theory predictions tested against > DESI galaxy survey data, september 2026 the idea that gravity emerges from entropy goes back to bekenstein in the seventies. the step here is a specific lagrangian that produces both the cosmological constant and a dark matter candidate from one source. none of this is confirmed. the math passed peer review in Physical Review D. the physics has no experimental support yet. connecting quantum gravity to the cosmological constant would change the field, but right now there is no observation to test it against. link to the paper in the comments

QUANTUM COMPUTER MADE PARTICLES FROM ENERGY there is a process in particle physics called string breaking. pull a quark and antiquark apart and the gluon field between them stretches like a rubber band. at some point the stored energy is enough to create a new pair of particles. matter appears where there was only force. this is how confinement works. quarks never exist alone because every time you try to isolate one, new quarks appear and pair up. similar dynamics played out in the early universe when quarks first became confined into protons and neutrons. a team at duke ran this on a quantum computer. thirteen trapped ytterbium ions in a chain, each one a site on a simplified lattice. laser beams controlled the interactions. they raised the string tension and watched charges appear. what they saw was unexpected. the standard picture says pairs should form along the entire string. here they formed at the edges and moved inward. a mechanism nobody predicted from a one-dimensional lattice. > duke: 13 trapped ions, 1d model, nature physics, > september 2026 > google: 45 qubits on sycamore, 2d model, nature, > june 2025 > quera: rydberg atom array, 2d with dynamical > matter, nature, june 2025 three teams, three platforms, same physics. none produced real quarks. the models are simplified and classical computers still handle this scale. the result matters for a different reason. for the first time quantum hardware simulated the strong force creating particles from stored energy. the models will grow. when they reach full three dimensions and hundreds of qubits, classical machines will not keep up. these simulators are being built for that threshold. link to the paper in the comments

AI FOUND THE STANDARD MODEL IN OLD DATA researchers at nyu abu dhabi fed a machine learning system particle data from the 1950s and 60s. masses, spins, decay modes. no equations and no guidance on what to look for. the system found baryon number. isospin. strangeness. charm. it sorted particles into the eightfold way, the classification gell-mann built in 1961. it found regge trajectories connecting mass to spin. this was not some massive deep learning model. they used pca, t-sne, and clustering. methods that have existed for decades. intro-level machine learning. the data has been sitting there since the 1950s. the patterns were in it the whole time. gell-mann spent years of theoretical work to see them. the algorithm found them with compute time and zero physics. > published in journal of high energy physics, > march 2026 > next step: can ai find quarks as building blocks > on its own > and can it infer gauge symmetries from field > theory data the question that follows: what happens when you point these methods at modern data. the lhc produces petabytes per year. most of it gets filtered through the standard model before anyone looks at it. patterns outside that framework would not survive the pipeline. a caveat. finding known patterns is a proof of concept. the real test is whether unsupervised methods catch something in data where nobody knows what to expect. that has not happened yet. the methods are cheap enough to try at scale, and the data exists. link to the paper in the comments

WARP DRIVE WITHOUT NEGATIVE MASS alcubierre figured out the geometry for a warp bubble in 1994. space contracts ahead, expands behind, ship rides inside in flat spacetime. the math worked. one thing it required: negative energy density. matter that probably does not exist. for thirty years that was where every warp drive conversation ended. last year fuchs and collaborators published a solution in classical and quantum gravity. same type of bubble. positive energy only. satisfies all three classical energy conditions. peer-reviewed. > works below lightspeed > needs roughly a jupiter mass converted to energy > no exotic matter required a jupiter mass of energy is beyond anything human civilization has produced in its entire history, by many orders of magnitude. and it only gets you below lightspeed. superluminal still requires exotic matter. what makes the result interesting: for thirty years the objection to warp drives was fundamental. you needed matter the universe probably does not contain. that objection is gone. what remains is a question of energy at a scale nobody can approach. the physics conversation about warp drives changed for the first time since 1994. link to the paper in the comments

THEY DROPPED ANTIMATTER for a hundred years we assumed antimatter falls down. the math said so, einstein said so, nobody argued. nobody tested it either. in 2023 the ALPHA team at CERN made antihydrogen, trapped about a hundred atoms in a magnetic bottle, and slowly opened it. if the atoms fall, most escape through the bottom. if they float up, most escape through the top. about 80 percent went down. > measured acceleration: roughly three quarters of g > precision: about 20 percent > published in Nature, september 2023 the number is rough but the direction is clear. antihydrogen was hard to test because it annihilates on contact with any surface. making it, cooling it, and holding it still long enough for gravity to win over thermal noise took three decades of engineering at CERN. several quantum gravity models predicted that antimatter would repel the earth. if that were true, you'd have a clue about dark energy and maybe about why the universe has more matter than antimatter. the experiment closed those models off. the 2024 run reproduced the result. three experiments — ALPHA-g, AEgIS, and GBAR — are racing toward one percent precision. they plan to laser-cool the atoms to about a thousandth of a kelvin and eventually use atomic interferometry. if gravity treats antimatter even a fraction of a percent differently, the data should catch it. for now the answer matched what everyone assumed. it just took until 2023 to have proof. link to the paper in the comments.
