Uh, thanks. Maybe I should write a book entitled "Cosmology Made Simple" :-).
But then I understand *nothing* of the ethereal and swampy parts of current
cosmological models - inflation, dark energy, cosmic strings, that sort of
ghostly stuff; I think that I understand 19th Century Physics only, and
that's all...

I didn't understand the question... :-(

Yes, I think that gravity alone is the main force orchestrating the "dance of
galaxies".
