Sometimes the Dark Matter, Dark Energy conversations reminds me of waves moving through aether
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.
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.
