Read up on the history of dark matter. THAT it exists is pretty firm. =20
In what exact form is an open question.

So are you saying that we have good reason to believe that most of
the matter of the cosmos is in a form that can be detected via
gravitational effects, unless there is something about matter,
gravitation or fundamental modeling assumptions that we are not
aware of, but we have no idea what it is, and a history of 40 years
of failure to find the most fashionable candidates?

That is your idea of a "firm prediction"? I would say it is more
of an indication that our understanding of the cosmos is extremely
limited. Not to mention grossly over-hyped.

I have studied all aspects of dark matter physics in great detail
-especially its history, thank you very much.

Yes.


but we have no idea what it is

Not quite -- we have some constraints on what it might be
(e.g., it's not "stuff that would emit visible light that would have
been detected by now")

and a history of 40 years
of failure to find the most fashionable candidates?

Yes.
