From them the God created everything.
But nobody knows, what is " virtual particles ","'dark matter'"
what is " latent mass ", " invisible particles ".
And then the physicists are very surprised :
"Why is the nature of the microworld so paradoxical ?"
We use words not understanding their meaning

When we say "dark matter" the words are not arbitrary.

Yes, they are. DM is not dark at all, so that term used to
describe it or even define it is clearly a misnomer no matter
how hard you wish upon a star that it isn't. In fact, DM can
be more accurately described as invisible matter because
we can see right through it, obviously. Physics is not all that
precise in term-usage as you once imagined, eh?

This hypothesized matter is called "matter" because it
has gravitational mass. It is called "dark" because it
isn't radiating energy we can see.

We assume it has gravitational mass, based on the
observed effects, but that conclusion is only one among
others that are possible; therefore, it is not a fact yet, as you
assert. Also, to say it is call "dark" because it does not
radiate is another phony explanation, since blackbodies do
not radiate either, they only absorb radiation. For such
absorption, they must have at least some gravitational
attraction, I would guess, and to have that requires real matter
having positive energy. Would it have politically improper
to call it "black matter" instead? Obviously, the most
appropriate term would have been "Invisible Matter", or, IM.

The closest thing to a blackbody I can think of is a black hole,
which is invisible to us because light cannot escape it. But we
could tell where a blackbody or a black hole may be located
because we do not see through them like we see through DM.
Since the two are not like DM, it should not be explained in
comparison to them.
