Interesting theory. It seems somewhat odd though. If you had to wait for the very small amount of heaver matter, to create supernovea; they slowly build the heavy matter around their core; and then wait untill they collapse and explode, this would take time longer than the universe exists itself; unless somehow they explode much quicker, because of their heavy matter, but why should buildup time take so long then?

When gas alone in universe creates stars, there should be much more non heavy matter stars, without planets/ unless in the mean while so much heavy matter has been created by supernovea, out of that tiny amount of left over, there is in the mean while heavy matter available everywhere. But that should involve an enormous leap in time.

All in all, it suggests that the concept of only helium as a beginning of the visual universe, is incorrect.

When gasclouds create stars, heavy matter already plays a role. So, where does it come from? Not just from supernovea left over and spread heavy matter.

Under what conditions helium only ends up as you describe? Is that a theoretical model? Or with no heavy matter involved. Of course, when heavy matter is involved from the start, because of the relation with dark matter at that spot in space, it does not come from anywhere else. So, the amount of left over heavy matter in helium, is much more than you suppose, that is in space on that spot.
