As you can read he

Jeans' length depends on T^(1/2) for constant mass density and constant G.
So, for high temperatures, the length is very big, allowing only for big
clouds to collaps, e.g. a proto-galactic cloud to form a galaxy, whereas
for low temperatures, also smaller clouds can collaps, e.g. a proto-stellar
cloud to a star.
What is the origin of these different
proto-galactic or proto-stellar cloud formation temperatures
in the context of the accepted
ubiquitous present CMBR 2.7 K temperature observation
that can be redshifted to any proto-galactic or proto-stellar cloud era
by (1+z)?
