A very interesting topic every day we human beings understand the universe better, but how can scientists know what dark matter is composed of? since it is invisible. How do you measure electrons, protons, neutrons, and neutrinos? that in theory dark matter is composed since we have no physical proof of it. Although it can be detected indirectly through gravitational influence, as the article says in general, although it is true that in recent years great progress has been made related to dark matter and I have spoken about it in one of my publications and now with the new theory of del bing bang Study reveals new details on what happened in the first microsecond of Big Bang I'm doing a short post on this topic. I recommend you read the article that leaves you thoughtful.

These types of topics leave more questions than answers
