As to how dust forms into rock/bigger mass the science research shows we simply don't know
not knowing is very different from knowing that it does not happen, which was your claim. Not knowing is also very different from having no idea. There are plenty of ideas, even in your own articles.
But how does any of this even relate to the topic of gravity? Gravity is proposed to be an important force in planet formation when the object is large enough for it to be.
If you think initial agglomeration of dust cannot happen, but that later gravity assisted accretion can, then you should be arguing that whatever processes that are involved in dust agglomeration are unnatural. Not gravity. We all agree that gravity can do what scientists claim it can do. Here you are - agreeing.
I accept what the science research is showing and that planetesimals can have gravitational when they reach a certain size.
