The biggest reason why we suspect the existence of dark matter is the fact that galaxies form clusters and super clusters. the distances are too big for them to be held by ordinary gravity.

Maybe there is a kind of gravity that results from atoms that is weaker than gravity but can on very large distances. I believe this is the first time this is being said. I can explain why...

I don't think you have this exactly right. The first mention I see is in measurements of the speed of rotation of galaxies. Some galaxies are seen to be spinning so fast that stars on the outer parameter should be flying off into space.
