Nearly a century ago, astronomers found that galaxies move as though they hold far more matter than we can see. Stars at the edges of spinning galaxies orbit too fast; the afterglow of the Big Bang bears the imprint of a substance …

For a century, "how fast is the universe expanding?" was a question answered by measuring. By 2026 the measuring had split: read from the afterglow of the Big Bang, the rate comes out near 67 (in astronomers' units); read from the local …

The Standard Model is the most successful theory ever built and the most unsatisfying: it predicts experiment to extraordinary precision, yet cannot say where its own numbers come from. Twenty-eight quantities — particle masses, force strengths, mixing angles — must be measured …

For half a century a quantum anomaly has been described as a flaw that shows up only when a classical symmetry is run through the quantum machine. This paper makes the opposite case: the anomaly is, at bottom, a classical and geometric …

Everything that stays itself has to pay for it. A cell, a flame, a spectrometer, a galaxy: each holds a pattern in place by taking energy in at one boundary and letting it out at another. Physics has been able to price …

Gravity is the shape of spacetime. The other three forces are not: they are rules attached on top of spacetime rather than properties of it, and physics has kept these two kinds of law in separate boxes for a hundred years. This …

Every electron in the universe is exactly like every other: the same mass, the same charge, the same spin. No electron has ever been seen to decay, or to reveal an inner structure. Two heavier copies of it exist — and only …

Complex numbers were invented in the sixteenth century to pass through the impossible square roots of the cubic; by 1925 they had become the working substance of physics, and the puzzle of why has stood ever since — posed at full strength …

Every particle discovered since the mid-1970s — the W and Z, the top, the Higgs — was on the Standard Model's list before it was found. This paper is about the first particle that is not on that list. GG-Theory derives, rather …

For 2300 years, the ideal of physical science has been Euclid's: a deductive system in which every theorem follows from a few postulates, with nothing left to fit. Modern physics drifted from that ideal — the Standard Model carries some 28 free …

For a century, quantum mechanics has been the most accurately tested theory ever written — and the least understood. It predicts the electron's magnetism to one part in ten trillion, yet no one can quite say why a measurement yields a single …

For forty years the standard model of cosmology, ΛCDM, has described the universe with breathtaking precision and explained almost none of it: a handful of numbers, read off the sky, reproduce everything — yet the theory cannot say why those numbers take …
