Unser Universum kann voller mikroskopischer schwarzer Löcher sein, und diese Idee gewinnt als überzeugende Erklärung für den Ursprung der dunklen Materie. „Die Idee ist sehr einfach“, sagt CERN -Forscher Dr. Franciolini. Und es erfordert „nichts jenseits des Standardmodells“ im Gegensatz zu vielen anderen Theorien.

I never understood this theory. I thought small black holes evaporate from Hawking Radiation very quickly?
Relevant xkcd: https://xkcd.com/2035/

I like the idea of using something as seemingly benign as rocks to help gather more information about the unknown universe. It makes the most sense – if it’s accurate and not too labor intensive – those things go all over the universe.
Could explain the Fermi paradox. Imagine flying into one of these.
I got called crazy for tossing this idea out there.
Obligatory link to the the short story „The blue afternoon that lasted forever“.
If you havent read it, do yourself a favour. Its great science fiction.

Seems unlikely as lots of small black holes don’t change the overall energy density of the universe, and one of the primary ways of measuring the amount of baryonic matter is the energy densities of cosmic microwave background.
There are other measurements such as gravitational measurements which ALSO line up with the cosmic microwave background measurements.
For this theory to be true, we would have seen a very different energy density in the CMB, and also we’d see differences in the helium / deuterium ratios after the Big Bang.
Also it’s been ages since I’ve sat through cosmology lectures, but I am pretty sure they thought of this a long time ago already and ruled it out for the aforementioned reasons.
