Sometimes the Dark Matter, Dark Energy conversations reminds me of waves moving through aether
As long as we are talking esotericlly, I think of fixed points on a primordial map. Like the fabric of everything and where the aether concentrates celestial bodies emerge. Like the backside of a cross stitch where we only see the stitch work rather than the image.
edit:
I don't know enough about black holes to speak credibly on the subject but another thought comes to mind.
Pretend there is a loading point for any fixed volume of space that when the gravity gets massive enough matter can collapse in on itself. That matter still exists but it now occupies space within matter.
I think dark matter is spot on. We're not finding it because it isn't a thing.
However... Relevant explanation of why people think there's dark matter.
Dark matter IS A THING. At least there is some thing out there that interacts weakly with the elctroweak force and interacts normally with gravity. We have plenty of evidence of it EXISTING. The problem of dark matter is we don't know what it is.... But sure as hell there is something. See the Bullet cluster if you don't believe me. And if you are a bit physics savvy, you can understand that it's evidence is imprinted in the CMB. We just don't know what it is.
Well I'm not the one to argue with you but dark matter is only a thing because our current assumptions are a thing.
If we had to change our thinking because of new knowledge of some fundamental assumption (such as the reason for red shift), it could very well do away with dark matter. I'm sure such a change of thinking will seem as ridiculous to scientists today as heliocentrism seemed to astronomers of Galileo's day.
I'm not saying this is the answer, but it's an alternative view. Unproven, but then again we can't find any dark matter either.
It is just not one observation that the new assumption has to fit. There are multiple options that fit some but not others, dark matter fits most we just don't know what it's made up of.
Yes, there may be an alternative answer. Just need to throw general relativity out of the window.
To be fair, future physics may indeed throw it away so there's that.
The gravitational effect is the only prerequisite. The WIMP theory predicts weakly interacting dark matter but even primordial nucleosynthesis does not require weakly interacting, just that it be nonbaryonic. So only if WIMPs are right is it going to be weakly interacting.
