Good science makes that a fact. Very good theory is nebula clouds to be
compressed by gravity need areas of heavy elements. These heavy
elements come out of super nova explosions and are traveling through
space as I'm typing(another source of dark matter(gravity) Best to
keep in mind where there is to much iron stars will not form(no fusion)
I could come up with a theory that supernova explosion that were 99%
more prevalent 19 billion years ago,and created dark matter(heavy
elements) that are detected only by the gravity they add to the universe
gravity. We observe this when we measure the angular force(spinning)
strong enough for spiral galaxies to fall apart,and don't. Bert

Ducky Wit since my thinking is so negative to your thinking This begs
the question Why don't you kill file me? best you do for I will always
keep posting my own ideas. I know my science,,and I taught myself to
add to books or discredit them as I like. and not what you like Go
figure Bert PS I don't kill file but will only from now on answer
your posts that are thoughtful Bert

You post bad science. I hate seeing idiots think they can get away with it.
Your thinking is muddled.

No heavy elements are needed for gravitational collapse although the
presence of molecules does allow a nebula to cool more efficiently as they
compress. This is thought to allow the collapse of smaller regions of the
nebula. The very first stars to form were most likely all high mass ones
until the intersteller medium was seeded with sufficient "metals" to
facilitate efficient radiative cooling. Dark matter BTW has nothing to do
with heavy elements.

Interesting is the calculations that put a lower limit on the mass of stars
formed during the populations. The earlier ones were probably at least 8 solar
masses (compared to a lower limit of 0.08 now) and were much higher.

In my day you had proper supernovae, not the ones you get these days !!
