Six years, 300 million galaxies, and the most precise map of dark matter ever made. The Dark Energy Survey's final results confirm the standard cosmological model — but also hint at tensions that could point to new physics.
One event per Planck four-volume gives a number with two hundred and forty-four digits, and it caps what a simulation can honestly render.
A numerical coincidence I could not explain turns out to be the standard exponential suppression with the coupling pinned by the central charge.
The derived capacity of the horizon, and the fraction of the holographic budget the old numerology was quietly using.
Two times the energy times the time, divided by pi hbar. Applied to a horizon, with three independent bounds agreeing.
A single coefficient that stood between a formula and a match, and where it came from, which is nowhere.
The primordial phase was presented as fixed by modular data. The channel and the prefactor were chosen to give pi over six.
Setting an expansion rate equal to a replication rate, differing by a factor of ten to the fifty-eight.
A critical acceleration whose stated formula evaluates to sixty-six per cent above the value claimed for it.
The worst single error in the programme, and the odd comfort that it was caught by its own printed arithmetic.
An identity I presented as independent confirmation, which is really a definition with a missing factor of omega lambda.
Another archived paper, and a note on why archiving beats deleting.
A likelihood pipeline built so that the framework can lose. That is the point of building it.
A clean idea with no mechanism behind the number it produced. Archived rather than deleted.
The claim that a phase is fixed by modular data, why that claim is weak, and the standard mechanism that supplies it instead.
A two-parameter fit that predicts the neutrino mass sum, followed by a leptogenesis claim that does not survive substitution.
A condensate at 10 to the minus 28 metres cannot explain galaxies. Add a horizon-set collective mode and it can reach them.
Two retractions, one derived capacity, and one exponent that matches to three parts in a hundred thousand.
Why an accelerating horizon looks hot to anyone inside it, worked through with a covariance matrix you can check.
The standard exponential suppression, and what happens when the coupling is pinned by a topological level.
