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?



I understand, that you dont understand GR!

DM interacts gravitationally, you could infer DM's existence
in deep space by G-lensing!

"You do understand this, right"?


and how will your lensing work if there is no MASS to create an Einstein Ring. That is "G-lensing" The definitions of a VOID in space is the fact that there is not detectable MATTER (radiating) in the VOID



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.


Oh, right! So I could use the same logic and conclude
that because isolated DM "hasn't" been 'detected' it can't exist!


Ergo, (according to you) "normal matter can exist "witout" DM,
but DM cannot exist without normal matter"?

Hmmmmmmmmmmmm!
And you know this; how?


and you are an EXPERT on DM and its effects. You claim DM is a particle and radiates.

ROFLMAO.


No it is DM because it DOES NOT RADIATE IN ANY FREQUENCY from LONG WAVE to microwave.


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*.



To use your own words;
"You don't have the faintest idea what you're talking about"!

Isolated DM could quite easily be detected *without* infering its
effects
on normal matter!

No it cannot. YOU NEED MATTER. beside only spintropic thinks DM has clumps.

Dark Matter is a puzzle. we found stars that have the WRONG rotation drop off. We found GALAXY GROUPS that are moving to fast and DO NOT ESCAPE. WE hypothesis DM is in effect. This is the only way we know about it.

questions:
is DM a global attribute? or is is specially associated with specific galaxies.

In most large galaxies there seem to be Black Holes. the size of a galaxy is defined by the black hole. SO we have BH , DM and a large Galaxy. What is the connection?

since NOBODY knows, why would clever ARROGANT spintropic know.

Unfortunately for you, however; NO isolated DM has been detected!

you're right No isolated DM has been detected. ( we only see bright galaxies doing strange things.)
