The week's question
In March 2025, in the thread "Re: OT, out", Umm asked the members: "Do you think it is because America is made up of magical soil that makes businesses based in America magically profitable?" This week it is put to everyone again. The button below opens the small thread re-asking it - read what others have said so far, then give your own answer as an ordinary reply.

"My theory is that there are trillions of dead galaxies and stars floating around, and with a black hole at the center we simply can’t see them because they’re, well, black. Not just the center: Including all the stars that circle and planets which circle them. They’re dead, you see. In space “dead” = “black”, at least at distance. Unobservable, unmeasurable.

Shortly after the Big Bang as energy accreted into matter it was still close together relatively speaking. Gravitational attraction would have formed stars, then galaxies *much* faster than we are used to today, and that led to billions or trillions of proto-galaxies forming within a few tens or hundreds of millions of years. They also burned out quickly because they were mostly gigantic, massive stars which can burn through their fuel in just a few million years, meaning it would be entirely possible for whole galaxies to have lived and died quickly and which would be unaccounted for (except by indirect gravitational measurements) in our “sighted” (visual, infrared, etc.) observations.

Get enough of those, impossible to see, not emitting any kind of radiation, and you have a huge source of matter which accounts for “the standard model” which is having trouble accounting for all manner of stuff.
"

Seems plausible.

Next step would be designing a set of observations in an attempt to bolster or detract from what is heretofore to be known as the Goofy Dark Matter Hypothesis.

Perhaps keep a directed search going in distant, dark areas for luminous bodies which geometrically accelerate, redshift, then vanish?
