How Dark Matter Was Born from the Geometry of the Universe ⚡ экспресс
Original: "Mimetic Dark Matter from Inflation"
The geometry of the Universe could have acted like a mixer, whipping up dark matter from the energy of expansion.

In the very first fractions of a second, the Universe inflated wildly. Scientists have figured out: thanks to a special geometry, in that frenzy, dark matter could have been born—the invisible dust from which galaxies later assembled. This explains why there's so much of it.
🎯 The amount of dark matter in this model required no fine-tuning—it just matched observational data, as if the geometry itself knew the right recipe.
🎬 Just as in the movie Interstellar, curved space influenced time, here geometry creates invisible matter.
\rho_{DM} \propto H_{\text{end}}^2
The amount of dark matter depends only on how fast the Universe expanded at the end of inflation.
