Dark matter is the ghostly realm. And boom, suddenly it hasn’t all been disproven :)

>And boom, suddenly it hasn’t all been disproven :) It still has been, because none of the claims made about ghosts can be explained by the known properties of dark matter (whatever it is.) For example, people claim to see ghosts, but dark matter doesn't interact with the electromagnetic spectrum. You can't see something that doesn't reflect light.

  Cameras can't see anything that doesn't interact with the electromagnetic spectrum, but most people see things that don't physically exist from time to time; they're called dreams or hallucinations, depending on context.

      That’s my point though - so far dark matter only exists in equations (and our imagination) and isn’t real (that we’ve been able to prove). It’s got as much proof as ghosts. That will surely change but we’re not there now.

Incorrect... there is plenty of evidence for dark matter beyond "equations and our imaginations[0,1]," and certainly more evidence for dark matter than for ghosts.

There is a recent take on dark energy though.
