Great article on an incredibly fascinating topic.

So dark matter ignores light as you say, but at the same time bends light due its gravitational interactions which it has in common with its sibling, the standard matter. In a way, similar to what standard matter black holes do, right? Hence the gravitational lenses caused by an otherwise invisible substance. So here is my question. By which observation can it be ruled out that dark matter is nothing but a gigantic network of countless standard matter black holes? If those had formed early on in huge quantities and scales, couldn't that explain the inhomogeneities wich we observe in the visible universe too?

Very much looking forward to this special event ;)
