I understand that the first cosmological computer simulations
Did not have DM
Only gas dynamics on expanding grids
And, that those sims produced no structure of any kind
No LSS
Only vast expanses of nearly uniform space plasma
Devoid of any clumps
Essentially reminiscent of the real actual voids
Which fill about 3/4ths of the volume of space
So simply stated, the first earliest computer simulations
Accurately reproduced VOIDS ...
In some sense they were 75% accurate...
But they never produced the large scale STRUCTURE
Particularly important to people upon this planet?
Hence the motivation for " something extra" ( people inserted DM ) to cause clumping into galaxies and clusters etc??
