  primitive galaxies.
  But data are not confirming the popular hypothesis that invisible dark matter
  helped the earliest stars and galaxies clump together.

Although MOND might appear superficially better on these selected data
there is an element of cherry picking going on.

It remains to be seen if fainter galaxies even further back are more as
CDM predicts. This stuff is right at the limits of detection for the WST
so it wouldn't surprise me if the brightest stuff is quite obvious and
more common than was expected whilst the faintest smaller objects though
more numerous are much harder to see.

Several new faint objects in the deep Hubble field have been missed
until very recently. There is a nasty and complex sampling interaction
between Lyman alpha emission being redshifted to a wavelength we can
detect which makes seeing things at this sort of redshift rather tricky.

I expect the same issue will affect WST in almost the same way.

Yes, there eis more to it
I was thinking about what Jeroen from CERN posted about  a paper that proposes
a spoce filled with some fluid..

That gives you propagation speed (of light for example) as function of density
of that fluid I would think,
and that density may have been dfferent at different times and in different places.

I see black holes spitting out matter that then form galaxies and those then form stars
like water coming out of a garden sprinkler in air.
So space is not ampty,
is it 'dark matter'?
And if then gravity moves at the speed of light then is it a form of some thing in that same medium?
As to MOND, from what I just wrote, the stars in the spiral arms are _not_ in orbit..
Just using Einstein's equations must go, we need a mechanism.
