So, if that is true, we would expect *not* to find a lot of dark matter
'between galaxies', wouldn't we?

Hmmm!

Let me think! DM aggregates galaxies! Fair enough!
Are you saying every "clump" of DM has aggregated a galaxy?

Prob not! So where are the isolated DM "Clumps" in deep space?

"Prob(ably) not" is not evidence, or even an educated guess.


So why would you expect "isolated DM 'Clumps' in deep
space", other than you think they should be there for some
unknown reason?

I know they aren't there!

No, you don't. Neither does anyone else, since the evidence
for the existence of dark matter is solely its effect on
normal matter. You do understand this, right?

Why do you insist there are isolated clumps of "normal matter"?
"For some unknown reason"?

Well, the fact that they've been detected has quite a bit to
do with it.

You can't have this both ways!

You don't have the faintest idea what you're talking about,
as is obvious by your attempt to use the argument "There are
no isolated clumps of dark matter in deep space", which is
something neither you nor anyone else knows, to try to
demonstrate...well...something obscure. I'm not sure even
you know what you're trying to prove with this bogus claim.
And there is no "have it both ways". Try to grasp this: We
directly detect *only* normal matter. We infer the existence
of dark matter because of the unexpected behavior of normal
matter; we can't directly detect it. If there's no normal
matter around (as is the case in most of intergalactic
space) there's no way to tell whether "clumps of DM" exist
there or not, since there's no normal matter, whose behavior
can show the presence of dark matter, to be affected, and we
*can't directly detect dark matter*.
