So let me get this straight. You asked for galaxies,

No I didn't!

Well, technically you asked for 'dark matter between the galaxies'. Now
then, right there is a problem... because the current understanding of
how galaxies form is that they form by dark matter clumps or 'halos'
attracting baryonic matter.

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?



so we cant mention a dark galaxy (regardless of whether this is where
most dark matter lies in deep space). But you're asking for an example
of dark matter where there is no matter.

Yes!

Well, what would that prove?


Me to be incorrect!



Since we assume 'dark matter' and 'normal
matter' were formed at the same time, and we know that 'dark matter' and
'normal matter' interact via gravity, why would we expect to find
instances of isolated 'dark matter'?


Your own logig betrays you!

You say DM & NM form in unison yet!

You say its "O.K" for "normal matter" to be "VOID" of DM.

So why not "DM" "VOID" of "normal matter"?



What would it show if we did? What
would it show if we didn't?


Me right or wrong!


You will NOT find isolated "DM".


But if dark matter is there, then
there is matter....

No!

Why not?


Just explained!


In what sort of bizarro universe does this logic work?

This one!

I don't think you're as smart as you make out,


TY, I didn't realise it came across so obviously!

and I don't think you
understand the theories that you presume to critique.

Thats not nice! But so what! ;-)
