A lot of you haven’t seen Angela Collier’s dark matter video and it shows.
Astronomers discover third galaxy lacking dark matter, challenging the assumption that dark matter is an invisible glue needed to hold galaxies together

… Is there anything preventing ‘dark matter’ or at least a substantial portion of it… from being just largely normal matter dust or gasses spread so thin we cannot 100% detect confirm detect them?

Well you see, the Immortal Science of Marxism-Leninism-Tankie Triad Thought States that Dark Matter is bourgeois, and that actually Galaxies are held together by the unwavering spirit of the Proletarian masses o7

I appreciate the reply but i posted on the wrong post for some reason 😂

Uuh, with three galaxies you can finally do some statistics on whether they are merely an outlier in a distribution or there is an actual mechanism at work here.

Van Dokum at it again?

Unless, hear me out here,
There’s this theory that there’s no such thing as Dark Matter; but rather, billions of free floating miniature black holes just wandering the cosmos as leftovers from the big bang.
What if the galaxies lacking “dark matter” are the ones where Type 3 civilizations have worked to capture, contain, and harness all these rogue black holes, especially if they may pose a threat to interstellar travel.

Note that it’s always good to keep in mind that “dark matter” is a scientific hypothesis at best, and really just a placeholder for trying to quantify some form of mass / effect that can’t be directly observed.
I love the black hole angle, though, especially as a bit of a Kurzgesagt fan.
Indeed, this one is probably the most fascinating hypotheses I’ve ever heard when it comes to cosmology:

(raise your hand and wave it around if you’re cool with living inside a black hole!)

Even though wikipedia calls dark matter an hypothesis it really isn’t. Dark matter is the observation, we see the gravitational effects of something that doesn’t seems to be there, mainly galaxies spinning faster than they should and light bending around clusters of galaxies more than it would bend otherwise.

The cool thing with this is if there are infinite universes where the laws of physics can vary, it could mean that every single fictional story within that range of laws of physics actually happened/is happening/will happen somewhere.
Like you can make up whatever story as long as it’s consistent and it will also be real. Though that “consistent” part might rule out a lot of stories involving lazy writing (though I suppose it depends on what kind of inconsistency it is… Like character trait inconsistency is possible but “laws of physics work differently based on what the plot needs” not so much).

That would make those black holes the dark matter.
Also why don’t they evaporate like other small black holes? Sorry I can’t watch your video right now.

All good, no apologies needed. It’s just a supposition at this point anyhow. But a coooool one

What if there is such a thing as dark matter, and galaxies lacking it are the ones where Type 3 civilizations burnt it all up for energy?

Wouldn’t the mass of those black holes still be there, acting like they did to speed up the galaxy?
