Astro Hacker News - 'Stupendously large' primordial black holes ruled out as a dark matter source

Not exactly related, but I've always wondered if a lot of "small" black holes not detectable disseminated inside a galaxy could serve as "glue" between all stars and give the impression of existence of dark matter.

Yes, that's one possible thing dark matter could be. Not sure what you mean by “give the impression of existence”, rock and magma gives “the impression of existence of a planet”.

Sounds like the next Star Wars script is coming along nicely. Less science, more fiction. Will no doubt be a big hit.
